Design of foundations rehabilitation of Faculty of Chemistry in Belgrade with analysis of MEGA piles' capacity

Abstract

This paper describes the solution of the rehabilitation of the foundations of the building of the Faculty of Chemistry in Belgrade, which suffered damage as a result of differential settlements, which happened several times during the exploitation. It was determined that the cause of settlements was moisturing of loess soil due to periodic watter spilling from da- maged water network. Rehabilitation is done by jacking of MEGA piles, which prevents the appearance of additional settlements. The rehabilitation was carried out in 2012-2013. In a second part of the paper, the evaluation of pile capacity prediction methods based on CPT test results is carried out by comparing with the measured pile jacking force.
