摘　　要：在总结缓倾状互层裂隙岩体的裂隙发育规律的基础上,给出了其裂隙网络生成方法;介绍了双重介质非饱和渗流理论,并基于此对缓倾状互层裂隙岩体的非饱和渗流场进行了分析,总结了互层状裂隙岩体降雨入渗条件下的非饱和渗流场的一些特征。Based on the review of the fracture development rules in inter-bed layered fractured rock mass, the fracture network generation method was provided, and then the double medium model was introduced. By use of the fracture network and double medium model the unsaturated seepage with rainfall infiltration in inter-bed layered fractured rock mass was analyzed, some characteristics of the unsaturated seepage with rainfall infiltration in inter-bed layered fractured rock mass was summarized.

关 键 词：层状岩体 双重介质模型 降雨 非饱和渗流场
