三峡库区滑坡地质灾害数量众多，主要诱因为降雨。以该地区具有代表性的土质滑坡土体为对象，综合考虑了三峡库区1971年至2003年的230次滑坡地质灾害与降雨因素之间的关系，进行了室内降雨模型试验的设计，以探究其降雨产流及入渗规律。通过对试验结果的综合分析及比较，揭示了相应试验工况下的降雨产流及饱和-非饱和-非稳定入渗规律、地表冲刷及裂缝发育情况，同时也分析了降雨强度、前期累计降雨量及坡角三个因子对降雨过程中的坡面产流及入渗的影响。
三峽庫區滑坡地質災害數量衆多，主要誘因為降雨。以該地區具有代錶性的土質滑坡土體為對象，綜閤攷慮瞭三峽庫區1971年至2003年的230次滑坡地質災害與降雨因素之間的關繫，進行瞭室內降雨模型試驗的設計，以探究其降雨產流及入滲規律。通過對試驗結果的綜閤分析及比較，揭示瞭相應試驗工況下的降雨產流及飽和-非飽和-非穩定入滲規律、地錶遲刷及裂縫髮育情況，同時也分析瞭降雨彊度、前期纍計降雨量及坡角三箇因子對降雨過程中的坡麵產流及入滲的影響。

There are numerous geologic hazards from landslide in Three Gorges Reservoir area,and the main inducement is rainfall.Here,taking the typical soil of this district’s landslide as the object,and considering the relationship between the 230 geologic hazards from landslide and the rainfall in Three Gorges Reservoir area synthetically,a series of indoor rainfall’s model tests is carried out to explore the rainfall runoff and infiltration law of landslide soil.With the synthetical analysis and comparison to the results of the tests,the rainfall runoff law and saturated-unsaturated and unsteady infiltra-tion law under corresponding test conditions are revealed,and the conditions of the surface erosion and fracture’s devel-opment under the corresponding test conditions are also revealed in detail.Simultaneously,the influencing ways of the rainfall intensity and cumulative rainfall and slope angle to the surface runoff and infiltration in rain process are analyzed.
