Abstract:The temperature effect of super-long concrete floor is so obvious that the tensile stress will easily lead to extensively slab crack. The temperature stress distribution in the concrete floor of a super-long underground structure is analyzed with FEM method, and some proposals, including optimization of structural arragement and new type of joint which is named as steel box deformation equipment, are raised.
