Abstract: On the basis of analyses in detail on identifying seepage free surface methods including residual discharge method, initial discharge method, imaginary knote discharge method and imaginary element method, global composite element iteration method, one revised one is given in this paper.And seepage free surface of rockmass slope of permanent shiplocks on the Three Gorges Project is researched by the method, which tallies quite well with both overflow zones and ground water level insitu.

Key words: seepage free surface, fixed mesh method, global composite element iteration method, application to shiplocks on the Three Gorges Project

摘要： 基于对渗流自由面求解的残余流量法、初流量法、节点虚流量法和虚单元法的详细分析,提出了复合单元全域迭代法,并据此研究了三峡工程永久船闸边坡的渗流自由面,其在边坡面的出溢点及地下水位与现场情况吻合.
