Abstract:Suzhou Central Plaza Project is a large-scale commercial complex project. The basement is developed as a whole. The underground outdoor wall adopts dual-purpose diaphram wall. The length of the basement is about 380 meters long, which is a super-long and large basement structure. The most unfavorable temperature conditions in Suzhou area were simulated, the effects of concrete shrinkage and creep and the reduction of interface cracks to temperature stress were considered, the finite element method was used to carry out detailed simulation analysis of the temperature stress problem of the structure. MIDAS Gen and YJK software were used for comparative analysis. According to the calculation results, the target is strengthened. On the basis of quantitative analysis, it is supplemented with other basement concrete crack control measures such as adding expansion agent and crack-resistant fiber to achieve seamless design.

Keywords:Suzhou Central Plaza; super long and large structure; dual-purpose diaphragm wall; finite element analysis; temperature stress
