| 摘 要： | 通过模拟降水过程中基坑的非稳定渗流,分析了降水过程中基坑整体稳定性的变化规律,探讨了非稳定渗流、基坑降水方案和渗透系数对整体稳定安全系数的影响。分析结果表明,渗流对基坑整体稳定性不利。在设计时只有充分考虑地下水渗流的影响,才能保证设计的安全性;渗透系数对整体稳定性的影响较大,对于渗透系数较大的土体,设计时可以按照稳定渗流计算基坑整体稳定安全系数,但要充分考虑降水速度的影响。

| Abstract: | The condition of the overall stability of foundation pit and the influence of unsteady seepage on its overall stability are discussed by simulating the unsteady seepage field in the process of lowering of ground water level. The computed results show that, the unsteady seepage is adverse to the overall stability of foundation pit,and therefore it is dangerous if the seepage is taken no account in the design practice;the coefficient of seepage is important to the overall stability and the speed of the proces... |
