正确计算地下水渗流过程中产生的水压力是评价滑坡稳定性的关键,然而目前有关地下水作用力的计算方法存有缺陷。为此,本文在两类地下水压力作用模式的基础上,对现有孔隙水压力和渗透力计算方法的合理性进行了探讨;在此基础上,采用以浸润线和渗流底边界为圆心确定等势线的流网模型对渗透力的计算方法进行了改进。研究表明,在流网模型基础上推导出的地下水作用力计算方法更为合理。
Correctly calculating the water pressure generated during groundwater seepage is the key to evaluate the stability of landslide. However, the calculation method of groundwater force is deficient at present. Therefore, on the basis of two kinds of groundwater pressure modes, this paper discusses the rationality of existing methods for calculating pore water pressure and infiltration force. On this basis, we use the boundary of infiltration line and seepage as the center of circle Potential flow network model to improve the calculation method of seepage force. The research shows that the calculation method of groundwater force deduced on the basis of flow network model is more reasonable.
