摘　　要：地下连续墙作为深基坑工程常见的围护结构形式,在施工工艺和质量风险防范措施上已取得了很好的发展,应用极为广泛。但通过多年工程实践经验的分析,采用不同的接头形式对地下连续墙施工质量、安全、进度以及造价控制的影响不同。通过具体的工程应用结果和数据分析,对近年来出现的套铣接头形式的施工工艺进行总结,并在技术、经济等方面与传统的锁口管接头形式进行对比分析。Diaphragm wall has witnessed a wide application.It is usually used as enclosure structure in deep foundation pit engineering,and its construction process and quality risk prevention have been obviously improved.After analysis on experiences in engineering practices for years,it is proved that different joint types produce different influences on control of construction quality,safety,schedule and cost of diaphragm wall.The construction process of washover joint type appearing in recent years is summarized through analysis on concrete engineering application and data,and contrastive analysis is made to traditional fore shaft pipe joint type on technical and economic aspects.
