抗滑桩加固边坡稳定性及影响因素的有限元分析
Finite element analysis for slope stability and its influencing factors with pile reinforcement
摘要
Abstract
A program named FPS was compiled with Fortran95 for the slope stability analysis with pile reinforcement,the results from FPS were compared with those from commercial software FLAC3D for validation, and the efficiency of FPS was discussed.Then the influences of the pile reinforcement parameters on the slope stability were studied.The results show that (1) when the pile length is shorter, it is suggested to drive pile at the lower part of slope; while the pile length is longer, it is suggested to drive pile at the middle of slope surface; (2) the effect of pile length on slope safety factor is related to pile location; when the pile is driven at the slope vertex or slope toe, the pile length has little effect on the slope safety factor; while the pile is driven at the middle of slope surface and before the pile length reaches the critical pile length, the safety factor increases greatly with the pile length in the linear relationship; (3) with the increase of pile length, the slope potential slip plane moves gradually to the inner place, failure mode of slope changes from shallow slipping to deep slipping, and the slope safety factor increases as well; but when the length of pile reaches some magnitude, the potential slip plane moves close to slope surface.关键词
