剩余推力法及其在斜坡稳定性评价中的应用

The remained slip force method considering the effect of rainfall and its application to assessment of slope stability

在总结已有研究成果的基础上,针对现有的剩余推力法计算公式中没有详细说明应如何考虑降雨的影响,以至在这一问题上目前还存在着很多模糊概念的状况,将降雨对斜坡稳定性的影响进行了系统分类,并尝试着给出了各影响因素的定量确定方法,然后在剩余推力法公式和程序中,加入了这些量化关系。将改进的剩余推力法应用于实例计算表明,计算结果符合实际情况。

For the existing remained slip force method, there is no description about how to consider the effect of rainfall, so there have many problems when we use it. To solve these problems, we categorized the effects of rainfall systematically based on the existing achievements; and have attempted to give out the ways of determining the effects quantitatively; then we added the quantitative relations into the existing formulas and programs. The application of the improved method indicates that the calculated result conforms to the reality.
