Experimental Study on Slope Stability with Soil Mixed Rocks under Rainfall

Article Preview

Abstract:

Rainfall is a key factor that triggers failure of slopes. Due to development of western China, there are more and more slopes with soils mixed rocks, with rainfall effect, some of them will fail, which will lead to loss of life and property. In this paper, a laboratory model was used to simulate to study slope failure of this type under rainfall. Along with rainfall, water infiltrated into the slope, and water content increased steadily and kept almost constant, settlement of inner zone increased with different magnitude and reached almost constant value, and cracks formed on the top, small scale failure occurred.
