In the present paper, the three dimensional seepage were analyzed by finite elements methods and Sand model examination for Fill type dam and Valley system. For the fill type dam and valley system are setting to the type (1) and the type (2) of the valley's form. THe type (1) is V model, and the type (2) is triangular prism model of the valley's form.A summary of results obtained is shown below ;(1) The chenginng in the factor, scale of crest length, slope and abutment of dam, were analyzed by finete element metords and the sand model examinations..(2) A seepage surface of shape are related these factors of dam.(3) The flow lines (h lines) of type (1) converges to toe drain of dam, but the type (2) are diffused to the lower reaches of dam.(4) The seepage points of type (1) are occurred in the high level of downstream slope under certain conditions.(5) These results cannot be obtained analyzes by the two dimensional seepage.

在本文中，通过有限的元素方法和填充类型大坝和山谷系统的砂模型检查分析了三维渗漏。对于填充类型的大坝和山谷系统，设置为山谷形式的类型（1）和类型（2）。类型（1）是V模型，（2）类型是山谷形式的三角形尖锐模型。获得的结果摘要如下所示；（1）通过因素，crest长度，坡度，斜率和基台的Chenginng，通过元素METORDS和SAND模型检查。 （1）收敛到大坝的脚趾排，但类型（2）被扩散到大坝的下部。（4）（4）类型（1）类型的渗流点发生在某些条件下的高水平下游斜率。（5）这些结果无法通过二维seepage获得分析。
