摘　　要：针对工程实际存在的饱和-非饱和边坡岩体等计算域内有密集排水孔的问题,引入排水子结构技术,推导了相应的计算公式,并开发了相关的程序,同时也简介了降雨入渗和饱和-非饱和渗流逸出面的正确模拟问题。最后对长江三峡永久船闸边坡降雨入渗饱和-非饱和渗流场问题进行了求解,分析和论证了工程中的有关渗流控制情况。To the unsaturated-saturated seepage field with densely-distributed drainage holes existing in the computational domain,the drainage substructure is introduced. The involved formulae are deduced and the com-putation program is developed. Meanwhile,rainfall infiltration and precise simulation of the exit face of the satu-rated-unsaturated seepage are also introduced. Finally,the problem of the slope seepage field of the permanent shiplock of the Three Gorges Project is calculated. The effectiveness and propriety of the seepage control measures in the slope are analyzed and verified.
