摘　　要：作为基坑开挖阶段的支护结构,PCMW工法可有效地保护周边环境。以采用了PCMW工法进行深基坑支护的南京市邮电大学科研综合楼基坑工程的设计和实施为背景,对PCMW工法中吊桩施工、支护管桩与冠梁、围檩的连接以及结合支撑的施工栈桥的设计等作了详细的介绍。设计过程中所采取的各种技术措施在工程实践中起到了良好的作用,可供类似工程借鉴和参考。The Prestressed Concrete Tube-pile Soil-cement Mixed Wall（ PCMW） construction method can effectively protect the surrounding environment as the supporting structure during the excavation stage of foundation pit. The design and construction of foundation pit project of engineering research complex building in Nanjing University of Posts and Telecommunications adopts PCMW construction method for deep foundation pit supporting,based on which the hoisting pile construction,connections between supporting pipe piles and crown beams,connections between supporting pipe piles and truss purlins,and the construction trestle design with supporting function were discussed in detail. The technological measures implemented in the design play a good role in engineering practice,which provides reference for the design and construction of similar projects.
