在一般土力学及挡土墙书籍中,介绍的土压力计算方法,均认为墙后土体是无限的,因而内破裂面能够完全形成(图1a)。但工程实践中有时却碰到墙后土体范围有限的另一种情况,这时由于墙背距坚实挖方、天然稳定山坡面或其他建筑物(为讨论之便,将其统称作限体)较近或与之相交,破裂面部分或全部受限而不能完全形成(图1b～e)。显然此时墙所受主动土压力将与一 In general soil mechanics and retaining wall books, earth pressure calculation methods are introduced, both consider that the soil behind the wall is infinite, so the internal rupture surface can be fully formed (Figure 1a). However, in engineering practice, it sometimes encounters the problem of a limited range of soil behind the wall. In this case, since the wall of the back is solidly excavated and the natural stability of the mountain slope or other buildings (for the sake of discussion, collectively referred to as the limit) Closer or intersecting, the fracture surface is partially or totally restricted and can not be fully formed (Fig. 1b-e). Apparently, the active earth pressure on the wall will be the same at this time
