摘　　要：三峡永久船闸系在天然山体中深切开挖修建，开挖后两侧形成高陡岩质边坡，高边坡稳定问题直接决定着船闸的成立与否和航运的安全。大量分析与研究表明，地下水是影响边坡稳定的主要因素之一。为确保高边坡稳定，根据高边坡基本设计方案，在船闸两侧边坡岩体内布置了由排水洞与排水孔幕组成的岩体地下排水系统，现场调查与地下水观测证实，地下水疏排效果显著，满足设计要求。The TGP permanent shiplock was built by means of excavation in natural rock mass of hilly area, and a high slop was formed. The stability of the high slop directly affects the establishment of the shiplock and the safety of its navigation. Studies and tests show that the stability of high slop is highly sensitive to underground water. In order to stabilize the high slop, an underground drainage system is designed and carried out. The investigation carried in site and monitoring data obtained show that the effect of the drainage system is remarkable to meet the design requirement.
