| 摘 要： | 排水孔是降低渗透压力以增强水工建筑物抗滑稳定性的重要措施，如何考虑排水孔的作用是渗流场分析中的一个难点。笔者提出夹层代孔列法，以等效排水夹层代替排水孔列，适当选择夹层的渗透系数，使排水夹层与排水孔列的排水效果总体上相等，采用本方法利用通常的三维有限元网格就可以分析含排水孔列的全坝三维渗流场，计算方便，效果良好。

| Abstract: | How to consider the effect of drainage holes is a difficult problem in the analysis of seepage field. It is suggested in this paper to substitute the curtain of drainage holes by a seeping layer the coefficient of permeability of which is so chosen that the draining effects of them are equal to each other. The results of computation show that the effect of equivalent seeping layer is practically equal to that of drainage holes but the computation is simplified remarkablely. |
