摘要: 裂隙岩体渗流及排水是三峡工程永久船闸边坡稳定与变形研究的重要内容. 而渗流模型的建立则是岩体渗流与排水研究的基础. 由渗透结构面可以比较客观地建立典型裂隙面渗流模型.基于实地调研, 永久船闸边坡岩体的渗透结构面可分为11组, 以NE ~ NEE向的陡倾角渗透结构面为主,据此在岩体等效渗透系数的求取及排水孔优化布设方向的确定方面得到了很好地应用.

Abstract: Seepage and drainage in fractured rockmass are important investigative topics on slope stability and deformation in permanent shiplocks of the Three Gorges Project, whose basis is founding the seepage model used in seepage and drainage studies. Discontinuum seepage model can be formed objectively with typical water-conduction fractures. On the basis of investigation in-situ, water-conduction fractures in slope rockmass can be divided into 11 groups in permanent shiplocks of the project, in which NE-NEE with steep dip angles are dominant water-conduction fractures. Hereby applications are reasonable on calculating of rockmass equivalent permeabilities and identifying of optimal design of drainage holes.
