| 摘 要： | 传统的深基坑支护计算方法比较繁琐,而假定的土压力与内力计算结果在许多情况下与实际情况不太吻合.本文将基于有限差分法,根据支护桩位移与土压力的关系,编制了一个迭代的计算程序模拟开挖的土压力变化,进而计算出基坑支护桩每一个点的内力与位移,提高了有限差分法的计算精度,方便进行设计优化和施工监测.

| Abstract: | Traditional calculation method of supporting structure in deep excavation is complex comparatively.The assumed lateral earth pressure and calculation result of internal force doesn't tally with practical situation in many cases.In this paper,according to the finite difference method and the relationship between the displacement and the pressure in retaining wall,it will introduce a iterative program to simulate the excavation lateral earth pressure,and to calculate the internal force and displacement of supporting pile.In this program,it also can improve the computing precision of finite difference method on excavation case,and provide the convenience to optimization of design and construction monitoring. |
