本文对于有限地面荷载作用下的多层土基坑提出了合理的土压力计算方法，并与梯形土压力分布模式进行了对比。

A new method of calculating soil pressure diagram for multi-layered soil excavation with finite surcharge is presented and the results are compared with those of the trapezoid soil pressure diagram.

土压力变化是土与挡土结构之间相互作用的结果，土压力的大小与分布模式同围护结构变形量和变形方式有关。

Change of soil pressure is the result of interaction between soil and retaining structure. Soil pressure level and distribution model are related to retaining structure deformation.

进一步研究了RB、RT模式挡土墙土压力的分布情况，并与T模式情况进行对比。

Further the earth pressure distribution with RB and rt modes was obtained using the same software, and the results were compared with t mode.
