| 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。

| Abstract: | 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. |
