摘要
从非饱和降雨入渗特性、堆积体滑坡稳定性评价方法、降雨诱发堆积体滑坡失稳机理三方面,综述了国内外降雨型堆积体滑坡渗流稳定性的研究进展。针对目前降雨型堆积体滑坡渗流稳定性研究中存在的不足,指出今后应明确降雨型堆积体滑坡的地质结构特征,深入研究渗流与径流的耦合机制及渗流地质结构力学参数的互馈耦合作用机制,加强降雨型堆积体滑坡的动态灾变机制研究,完善降雨型堆积体滑坡的安全性评价方法。
The research progress of seepage stability of rainfall-induced accumulation landslide both at home and abroad is reviewed from the aspects of unsaturated rainfall infiltration characteristics,evaluation methods of stability for accumulation landslide and instability mechanism of rainfall-induced accumulation landslide.In view of the deficiency in the study of seepage stability of rainfall-induced accumulation landslide,it is pointed out that the geological structure characteristics should be clarified.The coupling mechanism of seepage and runoff and the interaction mechanism of seepage-geological structure-mechanical parameters should be further investigated.The study of the dynamic disaster mechanism for rainfall-induced accumulation landslide should be strengthened and the safety evaluation method of rainfall-induced accumulation landslide should be improved in the future.
