基于ANSYS的L型挡土墙对比分析

he cross section of the L-shaped retaining wall is small,light weight,small amount of masonry,which is a relatively common retaining structure.In order to solve this problem, the engineers proposed secondary l-shaped retaining wall supporting structure. using ANSYS finite element software shows that,under the same condition, the safety factor of the secondary L-shaped retaining wall is higher, and the outer loads safety coefficient decreased slower; Secondary L-shaped retaining walls tend to slip damage, however L-shaped retaining walls tend to overthrow;Secondary L-shaped retaining walls with unloading platform similar to pour F type retaining wall, have obvious unloading relief effect; Secondary L-shaped retaining walls of basement pressure is small, suitable for the high slope of weak foundation supporting engineering;Design aspect, the secondary L-shaped retaining wall is more economic and more lightweight structure.
