Abstract: |
Rainfall infiltration is an important factor affecting the stability of the slope. Taking the high and steep slope of a mine waste dump as the research object, the change characteristics of the slope seepage field under different rainfall conditions were studied based on the saturated-unsaturated seepage theory. Unsaturated soil strength criterion and limit equilibrium method were used to analyze the stability of slope. The results showed that the range of slope transient saturation area was different with different types of rainfall infiltration. Under different rainfall conditions, the influence degree of slope stability was also different. The influence of posterior peak rainfall on slope stability was greater, while the influence of equal intensity rainfall on slope safety coefficient was relatively small. |
