Abstract

Abstract: The Three Gorges Project is one of the greatest hydroelectric projects in the world .Seepage and drainage in rock mass, which have important influences on stability and deformation of the permanent shiplock slopes, are the greatest research content in the course of some key techtoniques in construction of the shiplocks.In this paper , we expound drain mechanism of drain hole in drain tunnels, then point out two group advantageous design orientation for drain hole , and make a practical research on the basic model for drain hole to be designed in the slopes.

Key words: the Three Gorges Project, permanent shiplock, drain hole, drain mechanism, Optimal design

摘要： 融长、陡、高和重要性等四大要素于一体的三峡工程永久船闸边坡，对稳定和变形要求极其严格．岩体渗流与排水是永久船闸边坡稳定及变形研究过程中十分重要的研究内容．基于前期研究成果及实际情况，本文对边坡岩体的排水机理进行了较为深入的研究，提取出了山体排水孔的优势布设方向，进而提出了比较客观的山体排水孔布设的基本模式，其工程实用价值重大．更多还原
