（上海城鄉(xiāng)建筑設計院有限公司，上海 201103）[摘要] 在移位工程中，首先需要采用托換結構改變原結構的傳力途徑，然后通過液壓控制系統(tǒng)實現(xiàn)建(構) 筑物的移位。托換結構節(jié)點中經常采用的形式有抱柱梁、牛腿、夾墻梁形式，本文介紹上述三種形式的實際使用形式、受力機理、相關研究成果、設計建議，從而對移位工程的設計具有借鑒作用。[關鍵詞] 托換結構;抱柱梁;牛腿;夾墻梁中圖分類號：TU746.3 文獻標識碼：A 文章編號：1002-848X(2013)S2-0711-03作者簡介：顧遠生，碩士，中級工程師，一級注冊結構工程師，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
