Analytical Model for Prediction of Strains for Tunneling in Swelling Grounds
Publication: GeoFlorida 2010: Advances in Analysis, Modeling & Design
Abstract
Deformation of swelling rocks causing convergence in tunnels has always been an ambiguous issue. These deformations can lead to convergence and reduction of tunnels area. The aim of the current paper is development an analytical model using differential equations for formulating swelling strains as a function of time and stress. By this model, the swelling strains can be computed from the start of excavation to the time of installation of tunnel lining. The stresses of the surrounding tunnel due to excavation are calculated by Finite Element Method. These calculations are computed in MATLAB programming code. Results from this model indicated good compatibility with experimental results.
