Abstract

Based on the computing method of seepage-stress coupling and seepage analysis function of MIDAS/GTS, two-dimensional Numerical analysis of effect of water seepage in foundation pit near metro structure is study in this paper. The results are the method of "diaphragm wall+ inner support+ waterproof curtain" used in foundation pit support near to metro, can control subway sedimentation caused by water seepage during excavation effectively. Moreover, pore water pressure reduction and maximum sedimentation of the bottom of tunnel present parabolic trend with increasing excavating depth.
