The foundation was located at the high-water and deep sand formation, the surrounding environmental condition was complex. The design method of the diaphragm wall as the main body structure was analyzed, which including the layout of diaphragm wall as the main body structure, waterproof design of diaphragm wall joints, the analysis of the diaphragm wall method of the internal forces calculation. The results of the project implementation show that the diaphragm wall of joint of panels has good reliability and economy.Keywords: diaphragm wall; joint of panels; main body structure; waterproof design; super deep pit作者簡介：陳松，博士，高級工程師，一級注冊結(jié)構(gòu)工程師，Email:samboy2006@163.com。參考文獻［1］劉建航，侯學淵.基坑工程手冊［M］. 北京:中國建筑工業(yè)出版社,1997.［2］王衛(wèi)東.地下連續(xù)墻作為主體結(jié)構(gòu)的設(shè)計［J］.建筑結(jié)構(gòu)，2002，32(1)：3-8.［3］黃輝.地下連續(xù)墻接頭形式及其滲漏的防治措施［J］.施工技術(shù)，2004，33(10)：61-63.［4］翁其平，王衛(wèi)東，周建龍.超深圓形基坑逆作法“兩墻合一”地下連續(xù)墻設(shè)計［J］.建筑結(jié)構(gòu)學報，2002，31(5)：188-193.［5］郭宏智，唐玉文，王銀獻.作為地下室外墻及主體結(jié)構(gòu)承重墻和支護墻的地下連續(xù)墻施工難點及措施［J］.施工技術(shù)，2007，36(9)：17-19.
