摘要
本文运用裂隙岩体渗流模型与离散元力学模型耦合分析充水岩质高边坡的稳定性。根据裂隙岩体主干裂隙与网络状裂隙的特点，建立了的离散介质与连续介质耦合渗流模型并求其解。讨论了渗流模型与离散元模型耦合在边坡稳定性分析中应用的原理和方法。应用该方法对乌江构皮滩水利枢纽水垫塘两侧充水岩体的边坡稳定性进行了分析。
Thispaperpresents an approach forthe stability analysisofrock m assslopeby using distinctelem entm ethod coupled with fluid flow m odel. Tw o system s offracturescan be classified in a rock m ass:dom inantfracture system , in which fluid flow can be described by a distinctm edium m odel, and network fracture system , in which fluid flow can be denoted by a continuos m edium m odel. The principle ofdistinctelem entm ethod in com bination w ith flow m odelis dis- cussed in thepaper. Thisapproach isapplied in theslopestability analysisin Wujiang Goupitan Hydropow erProject.Re- sultsare used in the design ofthe project.
