（上海城乡建筑设计院有限公司，上海 201103）[摘要] 在移位工程中，首先需要采用托换结构改变原结构的传力途径，然后通过液压控制系统实现建(构) 筑物的移位。托换结构节点中经常采用的形式有抱柱梁、牛腿、夹墙梁形式，本文介绍上述三种形式的实际使用形式、受力机理、相关研究成果、设计建议，从而对移位工程的设计具有借鉴作用。[关键词] 托换结构;抱柱梁;牛腿;夹墙梁中图分类号：TU746.3 文献标识码：A 文章编号：1002-848X(2013)S2-0711-03作者简介：顾远生，硕士，中级工程师，一级注册结构工程师，Email：guyuansheng@gmail.com。Discussion on design of underpin structure joint for shift engineeringsGu Yuansheng(Shanghai Chengxiang Architectural Design Institute Co., Ltd., Shanghai 201103, China)Abstract: In the shift project, the force transmission route of original structure must be changed by underpin structure firstly, then the location of original structure shifted by hydraulic control system. Underpinning beam, corbel, jacketed wall beam always be used in the design of underpin structure joint. This paper introduces using formal, stress mechanism, related research results, design suggestions of the three above forms, thus, this paper about underpin structure joint for the shift engineering has reference.Keywords: underpin structure; underpinning beam; corbel; jacketed wall beam
