应用Green—Ampt（1973）模型解析三峡库区滑坡土入渗过程的探究

通过试验验证的方法探讨应用Green～Ampt（1973）理论解析模型推求三峡库区典型滑坡土体降雨入渗过程的可行性．研究中的试验设计为建立在对三峡库区滑坡地质灾害的分布及诱灾降雨进行调查统计的基础上，并考虑了Green—Ampt（1973）模型成立的前提条件．通过对试验及解析结果的对比分析得出的结论为，若用该解析模型来推求三峡库区滑坡土体的降雨产流及入渗过程，相关的边界条件假设、推导公式、计算参数取值等仍需大量的试验研究来改进与修正，同时给出了下一步研究工作的建议．

Application of Green-Ampt (1973) Model to Studying Rainfall Infiltration Process in Landslide Soil in Three Gorges Reservoir Area

Mainly by the way of model test, the paper explores the practicability through the theoretical model of Green-Ampt （ 1973 ） to calculate the infiltration process of typical landslide soil in Three Gorges Reservoir area. The experimental design of the research is based on the investigation and statistics of the landslide geo- logical disasters~ distribution of Three Gorges reservoir area and the disasters due to the rainfall, as well as considering the precondition of Green-Ampt （1973） model. ,Through comparison and analysis of the experi- mental and analytical results, the conclusion is drawn as follows. The assumptions of corresponding boundary condition, formula, and calculation parameters~ numerical value etc. , should be researched deep and bettered by lots of experiments. Finally, some suggestions are given for nest research work.
