| 英文摘要 | Rainfall is an important factor to trigger the debris flow. Numerical simulation on the responses of slopes and the initiation of debris flow under rainfall was processed by using the software FLAC2D based on the soil parameters in Weijia Gully, Beichuan County, Sichuan Province, China. The effects of the slope angle, rainfall intensity, soil parameters on the developments of the stress and pore pressure and deformation of the slope were studied. It indicates that large displacements of the slope are mainly located near the slope toe. With the increase of the rainfall intensity the stability of the slope decreases and so the debris-flow is easy to occur. |
