引入位移土压力理论的支护结构变形计算

The supporting structure deformation calculation introduced shift soil pressure theory

介绍了位移土压力理论,给出了引入位移土压力理论的支护结构变形计算,并结合具体工程实例进行了说明,指出对于小于5 m的基坑,运用位移土压力理论计算变形效果不明显,对于大于5 m的基坑支护结构的变形对土压力的变化会非常敏感。

The shift soil pressure theory was introduced, the supporting structure deformation calculation introduced shift soil pressure theory was given, which was illustrated with specific engineering example. It pointed out that the shift soil theoretical calculation deformation effect to the foundation ditch litter than 5 m was not obvious, while to the foundation ditch larger than 5 m, the supporting structure deformation was sensitive to soil pressure change.
