水利枢纽工程基坑降水问题的有限元分析

Finite element analysis of foundation pit drainage in hydro project

基于不同水文地质层水流运动特征的差异,基坑降水具体采用什么方式要根据工程的实际情况。用有限元法结合英布鲁水电枢纽工程,对降水方案选择、基坑防渗帷幕、排水沟、排水井对基坑渗流场的影响进行了研究。

Based on the discrepancy of stream in different hydrogeological stratum, the measure of foundation pit drainage should be carried out according to the engineering practice. In combination with the Yingbulu engineering, the author studied deeply, the influence of drainage plan drainage well pit impervious curtain, drainage ditch drainage well on seepage field.
