Diaphragm wall is interval or continuous casting sections of reinforced concrete walls, usually the connection between the two pieces of the wall is prepared ends all forms of templates. Diaphragm wall excavation technology originated in Europe, it is based on use of wells and oil drilling mud and water pouring concrete methods developed in 1950 in Milan, Italy for the first time using slurry diaphragm wall construction of protective wall, the 20th century 50-60 years in Western countries and the former Soviet Union have been promoted as underground and deep foundation construction of effective technology. First, Chinas hydropower sector in 1958 in Qingdao Dan bead reservoir dams built with this technology cut-off wall. If the envelope as the foundation of the underground continuous wall leakage of water, not only the excavation and the main structure will bring very negative impact on the construction, and will lead to foundation deformation and subsidence around the building is too large, and in severe Foundation instability occurs, collapse and other accidents, the parties to the project brought great economic losses and social impacts. Underground diaphragm wall as part of the main structure must be permanent and durable, the whole structure without penetration, seamless, force balance.  Key words: deep excavation; envelope; underground continuous wall  目 录 第1章 绪论 1 1.1 基坑工程发展状况 1 1.2 深基坑工程的内容 1 1.3 深基坑支护技术发展的前景 2 1.4 地下连续墙围护深基坑工程技术研究的目的和意义 3 1.5 研究内容 3 1.6 地下连续墙围护深基坑工程技术的适用及优缺点 3 第2章 基坑支护常用方法分析 5 2.1 基坑支护的基本要求 5 2.2 目前所采用的几种支护技术 5 2.2.1 钢板桩支护 5 2.2.2 深层搅拌水泥土桩 5 2.2.3 地下连续墙 6 2.2.4 钻孔灌注桩 7 2.2.5 土钉墙 7
