三峡永久船闸高边坡开挖及加固支护设计

永久船闸高边坡是三峡工程的重要建筑物，也是船闸结构的重要组成部分，规模巨大，技术复杂。确定合理的设计原则，选定合适的安全度标准，拟定合理的开挖形态和进行恰当的加固支护，制定合理的开挖与加固施工程序，确保边坡稳定和变形满足结构及运行要求是船闸高边坡设计中研究的主要问题。本结合围绕高边坡设计所进行的大量试验及分析研究成果，系统介绍了船闸高边坡的基本设计思想及开挖与加固支护基本设计方案。

Design of excavation and reinforcement support of high slope of Three Gorges permanent lock

The high slope of the permanent lock is an important building of the Three Gorges project, and it is also an important part of the lock structure. Determining reasonable design principle, selecting suitable safety standard, drawing up reasonable excavation form and proper reinforcement support, formulating reasonable excavation and reinforcement construction procedure, ensuring the stability and deformation of the slope to meet the structural and operational requirements are the main problems in the design of high slope of lock. This paper systematically introduces the basic design idea of high slope of ship lock and the basic design scheme of excavation and reinforcement support based on a lot of test and analysis results of high slope design.
