| 摘 要： | 本文从裂隙岩体非饱和渗流特性及参数、裂隙岩体浸润面的确定方法、渗流数学模型、工程应用研究等方面对高坝工程裂隙岩体渗流研究现状进行了系统的分析总结。当前,主要沿用多孔介质渗流的方法研究裂隙渗流,所建立的裂隙岩体非饱和渗流水力参数关系还不能真实反映裂隙渗流的特性;连续介质-非连续介质渗流模型能够较好反映裂隙岩体的空隙结构和渗流特性,要继续研究相应的数值计算方法;库水位升降变化及降雨影响下库岸边坡岩体渗流是饱和-非饱和非稳定渗流,应将饱和区与非饱和区统一起来分析。

| Abstract: | This paper makes a systematic study for the current situation of seepage in fractured rock mass from some fields such as seepage characteristics,unsaturated hydraulic parameters for unsaturated flow,determination of the free surface,simulation models and its application in reservoir engineering,etc.At present,the method of analyzing seepage for porous media is still a main means for fluid flow in fractured rock mass,but the results usually can not be a true reflection of characteristics for hydraulic parame... |
