Subsidence due to lowering groundwater level

Abstract

Subsidence due to lowering groundwater level, is often neglected problem. Detailed description of the problem is presented in the paper and model for calculating subsidence is elaborated. Model calculates vertical one dimensional deformations in time. It is based on well known theorethical solutions that are slightlz adopted to fit this problem. In the presented model, solving the problem of groundwater dynamics and subsidence in time are separated, meaning that change of groundwater levels is inut for subsidence calculation.

Sleganje tla koje je posledica sniženja nivoa podzemne vode je u velikoj meri zanemaren problem. U radu je ovaj fenomen detaljno analiziran i prikazan je model za proračun sleganja koje je posledica sniženja nivoa podzemne vode. Model se zasniva na proračunu jednodimenzinalne vertikalne deformacije u vremenu i zasnovanje na poznatim teorijskim postavkama i rešenjima, koja su delom prilagođena ovom problemu. Model se zasniva na razdvajanju problema sleganja i dinamike kretanja podzemne vode, što znači da su promene nivoa podzemne vode ulazni podatci za modeliranje sleganja u vremenu.
