| 摘 要： | 通过都江堰某不稳定斜坡变形监测与模拟计算，对该斜坡在持续降雨条件下稳定性进行分析评价。通过改变坡体的物理参数来模拟持续降雨条件，计算时采用极限平衡法中的传递系数法。通过位移监测与计算分析，结果显示，随着持续降雨，斜坡稳定性不断降低，最终达到不稳定状态，应进行加固处理，以保安全。

Analysis on Influence of Continuous Rainfall on Slope Stability |
| |
| Abstract: | Through monitoring the deformation of an instable slope in Dujiangyan and the related simulation computation, its stability under the condition of continuous rainfall was analyzed and evaluated. By changing the physical parameters of the slope to simulate the condition of continuous rainfall, transfer coefficient method in limit equilibrium method was adopted in the computation. The results of displacement monitoring and computation show that, as rainfall continues, the slope stability decreases and reaches a state of instability finally; hence it should be reinforced and protected for the sake of safety. |
