摘要
笔者对三峡工程永久船闸排水洞中的仰、铅两种布设方式的排水孔进行了排水量实地观测．结果表明， 仰孔的排水效果明显优于铅孔． 再对排水洞的结构面及排水孔穿过结构面的数目分析，其理论分析结果与实测基本一致．
Drainae discharge of upward and plumb drainage hole at Permanent Shiplockes in the Three Gorge Project was measured in situ.Result shows that drainage effectiveness of upward hole has an obvious advantage over that of plumb hole.We have analyzed discontinuities in drainage gallery and numbers that drainasge hole pass through discontinuities in terms of theory.Theroretical result is the same as the measured result in situ.
