边坡稳定性分析中水作用力计算方法研究

Study on Calculation Method of Water Active Force in Slope Stability Analysis

水作用力计算的正确与否对边坡稳定性分析结果有着重大影响,然而当前计算水作用力的方法有缺陷。文中在力的正确选取的前提下确定了两类水作用力的计算模型,在此基础上对现有常用方法进行了合理性分析。提出了边坡稳定性分析中单个条块的地下水流网形态,导出了新的水作用力计算方法。

Correct calculation of water active force plays an important part in the result of slope stability, but the current calculation methods for water active force is still defective. This paper determines two calculation models for water active force under correct selection of force and, on the basis of it, analyzes the rationality of the current common methods. It puts forward underground water flow network of single block in slope stability analysis and educes new calculation method for water action.
