| 摘 要： | 以太原市某工程为例，从实际的基坑设计中得出，基坑支护中土压力设计值一般都比实际值偏大；支护桩周围的土压力的主动区、被动区并不是一成不变的。提出用位移分析的土压力模型来区分实际工程中的主、被动区，而后进行土体受力定量的分析。

| Abstract: | Taking an engineering of Taiyuan City as the example, and according to the actual foundation pit design, this paper expounds that the design value of the earth pressure in the foundation pit support is generally more than the actual value and the active earth pressure zone and the passive earth pressure zone around the support pile is variable, and points out that should distinguish the active earth pressure and passive earth pressure in actual engineering by using the displacement analysis, and then make the quantitative analysis on the stress of soil. |
