摘要
分析了斜坡坡面遭受天然降水与人类活动的侵蚀破坏对坡体稳定性的影响,认为坡面裸露的黄土边坡在长期的雨水冲刷与入渗情况下,坡面侵蚀破坏成为滑动面位于土层中的黄土边坡渐进破坏的诱发与促进因素。并对其失稳机理进行了探讨。
The erodible factors of loess slope surface are analyzed, including the rainfall and human activities which affect the stability of the loess slope. It is considered that the slope surface erosion is the inducing and promoting factor of the gradual destruction of the loess slope in long-term rainfall wash and infiltration, whose surface is exposed and within which is the slippage interface. Finally, the mechanism of losing stability in the loess slope is studied.
