摘要
综述了国内外裂隙岩体(主要是细、微裂隙岩体)非饱和渗流的研究情况.首先,评述了现有的测定和确定单裂隙非饱和水力参数的几种方法的优缺点,为单裂隙非饱和水力参数的确定提供了理论依据.其次,分析了目前用于求解裂隙岩体非饱和渗流的四种数学模型的优缺点,为选取合理的数学模型用于求解具体的裂隙岩体非饱和渗流问题提供了参考依据.最后。
In this paper,the research of unsaturated seepage flow in fractured rock masses at home and abroad is systematically reviewed(here,the fracture mainly means fine or tiny fracture).Firstly,the advantages and disadvantages of present measurement and determination methods of unsaturated hydraulic parameters for a single fracture are commented upon.These comments provide a theoretical basis for the determination of unsaturated hydraulic parameters for a single fracture.Secondly,the advantages and disadvantages of four mathematical models currently used to solve unsaturated seepage flow in fractured rock masses are analyzed,and their application in engineering is also introduced.These analyses provide reference for the selection of proper mathematical models used to solve specific unsaturated seepage flow in fractured rock masses.Finally,some problems are put forward which need to be further researched.
