摘　　要：结合工程实际,对渠式切割组合式地下连续墙(TAD工法)在大型机场交通枢纽工程中的应用进行了研究。详细阐述了TAD工法的施工工艺,并在施工前对TAD工法的施工效果进行了试验。结果表明,TAD工法止水性能较好,墙体刚度较大,且在施工过程中对周边环境施工影响小,可以作为上海软土地区基坑工程围护结构的一种新型工艺进行推广应用。Based on the engineering practice,the application of trench cutting assembled diaphragm wall(TAD construction method)in large airport transportation hub project is studied.The construction technology of TAD method is described in detail,and the construction effect of TAD method is tested before construction.The results show that the TAD construction method has good water sealing performance,high wall stiffness and little influence on the surrounding environment during the construction process,which can be popularized and applied as a new technology for the enclosure structure of foundation pit engineering in soft soil area of Shanghai.
