AB  - Advanced numerical methods, such as the finite element method (FEM), are widely used in geotechnical engineering practice to predict displacements induced by deep excavations and tunnel construction. While the finite element method is primarily used to obtain displacements and hence to verify serviceability limit states (SLS), it is also increasingly used for geotechnical ultimate limit state (ULS) design. The introduction of the Eurocode 7 and the associated concept of partial safety factors has replaced the global safety factor concept which had previously been used in geotechnical design practice. Eurocode 7 introduces partial safety factors on actions (loads), materials and resistances. Three design approaches (DA1, DA2 and DA3) that differ in the combination of partial factors are available in the current version of Eurocode 7, however, the guidance as to how the partial factors should be applied in numerical analysis is not provided. The second generation of Eurocode 7 is currently being prepared, and the proposed draft of Eurocode 7 Part 1 (EN 1997-1:202x) contains a new set of rules covering geotechnical design and the verification of limit states using advanced numerical methods. In order to ensure sufficient reliability in relation to the ultimate limit states occurring in the ground and structural elements, two combinations of partial safety factors have to be applied, i.e. ULS verification with numerical models has to be performed by reducing the ground strength parameters and by increasing the structural forces in accordance with applied design approach. Although Eurocode 7 has no specific parts devoted to the design of tunnels, it is increasingly used in practice, at least for shallow tunnels in soil, since there are no European standards for tunnel design.This paper gives an overview of the procedures for applying  finite element method and design approaches defined in Eurocode 7 to design of deep excavations and tunnels.

AB  - The design of urban tunnels, often constructed at shallow depths, in soft ground, requires an appropriate prediction of ground surface settlements. Control of surface settlements is of particular importance in open-face tunneling. This paper presents a finite element analysis of subsidence above conventionally constructed Steinhaldenfeld tunnel in Stuttgart, Germany. The surface settlement profiles obtained by calculations were compared with the empirical Gaussian curve and the profile obtained by measurements.

AB  - Results of a series of 3D and 2D analyses of open-face tunnelling in marly-clayey deposits are presented in the paper. A parametric study was performed to investigate the influence of initial stress state, soil deformability, shear strength parameters, and soil anisotropy, on settlement prediction. Comparison of 2D and 3D results shows that the settlement trough predicted by 2D analysis agrees well with 3D results when an appropriate amount of unloading prior to lining installation is adopted. It is demonstrated that the load reduction factor significantly depends on shear strength parameters of soil.

AB  - This paper presents the results of laboratory research of fly ash soil stabilization. Tests were performed on mixtures with high plasticity clay and fly ash sampled from thermal electric power plant ”Kostolac”. Effects of fly ash on moisturedensity relationship, UCS, CBR, deformation parameters and swell potential were evaluated. Results of the research indicate that fly ash can improve some engineering properties of this type of soil. The most significant improvement is the increase in CBR values which makes this material usable for road construction.
AB  - U radu su prikazani rezultati laboratorijskih ispitivanja stabilizacije gline visoke plastičnosti primenom letećeg pepela iz TE Kostolac. Ispitan je uticaj pepela na odnos vlažnosti i suve zapreminske težine, jednoaksijalnu čvrstoću, CBR, module deformabilnosti i potencijal bubrenja. Dobijeni rezultati su pokazali da se primenom pepela kao stabilizatora mogu poboljšati neke inženjerske karakteristike ove vrste tla. Najveće poboljšanje je porast CBR vrednosti, što ovo tlo čini upotrebljivim u putogradnji.

AB  - Results of laboratory research focusing on soil stabilization, using fly ash without activators, are presented in the paper. Two types of fine-grained soils were tested: low to medium plasticity clay and very expansive, medium to high plasticity clay. Soil-fly ash mixtures were prepared at optimum fly ash contents (15 and 20%). The effects of fly ash on the soil plasticity, moisture-density relationship, unconfined compressive strength, shear strength parameters, CBR (California Bearing Ratio) values, deformation parameters, and swell potential, were evaluated. Results obtained show that the use uf fly ash can significantly contribute to the improvement of soil properties.

AB  - U radu su prikazani rezultati laboratorijskih ispitivanja stabilizacije gline visoke plastičnosti primenom letećeg pepela iz termoelektrane Kolubara, sa i bez aktivatora cementa ili kreča. Ispitan je uticaj pepela na odnos vlažnosti i suve zapreminske težine, jednoaksijalnu čvrstoću, parametre smičuće čvrstoće, CBR, module deformabilnosti i potencijal bubrenja. Dobijeni rezultati su pokazali da se primenom čistog pepela kao stabilizatora mogu poboljšati neke inženjerske karakteristike ove vrste tla, dok su sa dodatkom cementa ili kreča zabeleženi značajni efekti stabilizacije.

AB  - This paper presents the results of laboratory research of high plasticity clay stabilization using non self-cementing class F fly ash (also known as pulverised fuel ash or PFA) with and without activator - cement. Fly ash was collected from Serbian electric power plant "Kostolac". Soil-fly ash mixtures were prepared at different fly ash contents (10-25%). Tests were conducted on specimens compacted at the optimum water content from Standard Proctor compaction test. Effects of fly ash on physical and mechanical properties of soil such as plasticity, unconfined compressive strength, effective shear strength parameters, CBR, deformation parameters and swell potential were evaluated. Results of the research indicate that used fly ash without activator can effectively improve some engineering properties of the soil. After addition of cement the stabilization effects substantially were improved.

AB  - The rapid urban development, in recent decades, has led to increasing demands for construction and expansion of the underground transport network in large overpopulated cities. An important task in the design of tunnels in urban areas is to adequately predict the ground surface subsidence. This paper presents the methods for 3D and 2D finite element modelling of tunnel construction. Also, the paper presents some results of analysis of the ground surface subsidence due to tunnelling in Belgrade marly clay. This is a current problem given that the start of the Belgrade metro construction is planned in the near future.

AB  - This paper presents the results of laboratory research of fly-ash soil stabilization. Tests were conducted on mixtures with alevrite - very expansive, medium to high plasticity clay and fly ash sampled in thermo electric power plant ”Kolubara”. Effects of fly ash on physical and mechanical properties of soil (grain size distribution, Atterberg limits, moisture-density relationship, unconfined compression strength, effective shear strength parameters, CBR, deformation parameters, swell potential) were evaluated. Results of the research indicate that fly ash can effectively improve some engineering properties of soil. The most significant improvement is the increase in CBR values and reduction of swell potential because it makes this material usable for road construction.

AB  - This paper presents the results of laboratory research of fly-ash soil stabilization. Tests were conducted on mixtures with two types of fine-grained soils and fly ash sampled in Serbian electric power plant Kolubara. Used types of soils are low plasticity silty clay and very expansive, medium to high plasticity clay. Effects of fly ash on physical and mechanical properties of soil (grain size distribution, Atterberg limits, unconfined compression strength, moisture-density relationship, swell potential, CBR) were evaluated. Test mixtures were prepared at optimum water content from standard Proctor compaction test. Results of the research indicate that fly ash can effectively improve some engineering properties of soil.

AB  - In the analysis of tunnel lining - rock mass interaction, it is essential to consider partial stress release at the tunnel face, i.e. deformation of the tunnel walling that occurs before the application of the lining. Accordingly, it is important to develop an adequate numerical model considering tunneling face effects as well as construction sequence effects. Consequently, a 3D numerical modelling is necessary. Through the use of finite element method (FEM), a numerical model is developed enabling analysis of stress-strain states considering specific rock mass properties and consequent stages of a tunnel construction. In this first paper, some elements of FEM modeling of rock mass and tunneling were introduced. 3D numerical modelling of tunnel driving process is described: treatment of construction stages, and iterative procedure for simulating the tunneling face advancement. .
AB  - Kod razmatranja problema interakcije tunelske obloge i stenske mase od suštinskog značaja je razmatranje delimične relaksacije stenske mase, odnosno pomeranja konture iskopa koja su se desila na čelu tunela pre postavljanja obloge. U tom smislu izuzetno je značajno definisanje adekvatnog numeričkog modela. 3D numeričko modeliranje neophodno je za razmatranje efekata na radnom čelu tunela kao i efekata sekvencijalne izgradnje tunela. Metodom konačnih elemenata razvija se model sa kojim se može sprovesti naponsko-deformacijska analiza po fazama građenja sa uzimanjem u obzir odgovarajućih svojstava stenske mase. U ovom prvom radu se razmatraju neki problemi modeliranja stenske mase i tunela metodom konačnih elemenata. Prikazano je 3D numeričko modeliranje izgradnje tunela pri čemu je analiziran tretman faza građenja i izložen iterativni postupak za simulaciju napredovanja čela tunela. .
