摘要: 受運(yùn)輸及起吊能力的影響,單幅預(yù)制地下連續(xù)墻的長度和重量受到限制。 為推廣預(yù)制地下連續(xù)墻的應(yīng)用,對地下連續(xù)墻進(jìn)行分節(jié)預(yù)制、現(xiàn)場拼裝連接是一種有效可行的方案。 提出一種分節(jié)預(yù)制地下連續(xù)墻螺栓連接橫向接頭方案,利用 1:1 模型試驗(yàn)的方法對橫向接頭的承載力及剛度進(jìn)行分析,并將提出的分節(jié)預(yù)制地下連續(xù)墻螺栓連接橫向接頭方案應(yīng)用于某地鐵車站附屬基坑工程中。 模型試驗(yàn)及工程實(shí)踐均證明,分節(jié)預(yù)制地下連續(xù)墻螺栓連接橫向接頭具有足夠的強(qiáng)度與剛度,能夠滿足車站附屬基坑開挖、回筑及結(jié)構(gòu)使用和防水的要求,效果良好。

Abstract:Affected by transportation and lifting capacity, the length and weight of a single prefabricated diaphragm wall arerestricted. In order to promote the application of prefabricated diaphragm walls, it is an effective and feasible plan to carryout segmental pre ̄cast and assembling segmentally on site for diaphragm wall. A plan for bolt connection transversal joint ofsegmental pre ̄cast diaphragm wall was put forward, and the bearing capacity and rigidity of the transverse joints wereanalyzed by 1:1 model test, and the proposed plan for bolt connection transversal joint of segmental pre ̄cast diaphragm wallwas applied in a subway station subsidiary foundation pit project. Model tests and engineering practice have proved that thebolt connection transversal joint of segmental pre ̄cast diaphragm wall has sufficient strength and rigidity to meet therequirements of the excavation of the subsidiary foundation pit of the station, rebuilding, structural use and waterproofing,and the effect is good.
Keywords:segmental pre ̄cast diaphragm wall;bolt connection transversal joint;bearing capacity;rigidity
