通过试验模拟天然降雨条件,研究了不同的降雨强度、降雨历时、累积降雨量对碎石土边坡不同部位水压力的影响,分析了降雨作用下碎石土边坡的变形破坏机理及降雨诱发滑坡的主要作用方式。试验结果表明,降雨强度、地下水位、降雨持续时间是影响坡体稳定的重要因素。
The effects of different rainfall intensity, rainfall duration and cumulative rainfall on water pressure in different parts of the gravelly soil slope were studied by simulating the natural rainfall conditions. The deformation and failure mechanism of the gravelly soil slope under rainfall and rainfall-induced Landslide’s main mode of action. The test results show that rainfall intensity, groundwater level and rainfall duration are the important factors affecting the stability of slope.
