地铁车站诱导缝设置参数分析
Analysis of Setting Parameters for Induced Joint in Subway Station
摘要
Abstract
The subway station is composed of underground continuous wall,lining wall,bottom plate and top plate.The crack of roof and lining wall has always been a problem in design and construction.The induced joints of subway station structure can reduce disorder cracking induced by temperature stress of the concrete structure during the construction and operation of subway station structures.Based on Qingpu Station of Shanghai Metro Line 17,numerical analysis is conducted by finite element method.The factors for distance of induced joints,the thickness of the lining wall,the separation and integral pouring of the roof and lining wall are addressed.The results show that the stress of the lining wall and roof is reduced after induced joints are put in place.With the increase of the distance of induced joints,the stress of the lining wall and roof decreases gradually.Meanwhile,the stress of the lining wall and roof decreases gradually with the increase of lining wall thickness.When the top lining wall and roof are poured separately,the stress of the top lining wall and roof is larger than that of the integrated casting.The results may provide optimization measures and suggestions for setting induced joints to prevent cracks in the subway station.关键词
