［摘要］详细介绍了目前在逆作法施工中得到广泛应用的地下连续墙墙段之间、地下连续墙与梁板之间以及中间支承柱与梁之间节点连接的处理，并对其施工工艺的优缺点以及各自的适用性进行了对比分析，以期能较好地解决逆作法施工节点连接中存在的问题，并为同类工程的设计施工提供借鉴。

［关键词］逆作法；节点连接；地下连续墙；梁板；中间支承柱

Abstract:Disposals of joint connection between underground continuous wall segments,underground continuous walls and beam-slabs as well as middle support columns and beams which are widely used in the top-down construction were introduced in detail. The advantages,disadvantages and applicability of the construction technology were compared and analyzed in order to solve the problems of the joint connection in top-down construction and provide reference of design and construction for similar projects.

Keywords:top-down construction technology; joint connection; underground continuous wall; beam-slabs; middle support column
