浅议斜坡稳定性计算中水压力的作用

理论推导证明了静水压力模式与动水压力模式下地下水作用效果的差异,并且结合前人的研究成果,提出要取得合理的稳定性计算结果,两种水压力模式下所选用的强度参数应有所区分,对于静水压力模式,应取快剪或不排水剪指标;对于动水压力模式,则应取用慢剪或排水剪指标。最后采用一个具体的工程实例验证了结论的合理性。

Briefly Discussion of the Function of Water Pressure in Calculation of Slope Stability

In this paper, the difference of the two modules was firstly clarified based on theory analysis, and then, the following conclusions were drawn out: to get reasonable stability analyzing result, different intensity parameters should be taken according to the hydraulic pressure module. When using static hydraulic pressure, the quick shearing or un-drained shearing parameters should be adopted, while, when using dynamic hydraulic pressure, the slow-shearing or drained shearing parameters should be adopted. In the last part of the paper, an engineering example was used to prove the rationality of the above conclusions.
