Study on the Effect of Slope Stability by Bedrock Softening under the Condition of Strong Rainfall Infiltration

摘要：

In recent years, the extreme weather has caused a serious effect to the engineering, strong rainfall is the important reason result in debris flow frequent happens. For the problem of slope stability under the condition of strong rainfall, this paper adopted the strength reduction by FEM, combining case of slope, analyzed the causes the bedrock soften under the condition of normal and strong rainfall separately, band slope appears the phenomenon of saturated water softening under strong rainfall, an d its physical mechanical properties and strength greatly reduce. The conclusion can be obtained that the problem of slop safety and stability is caused by bedrock softening. Following bedrock strength decreases by step, then slop loses safety and stability.
