摘　　要：本文结合工程实例,采用PMSAP有限元分析某商业综合体超长地下室结构在温差效应下对结构的不利影响,在此基础上相应采取设置后浇带、混凝土配合比优化、混凝土浇筑跳仓法施工、温度应力较大的地方采取提高配筋率、钢筋细密化布置等措施来解决超长地下室裂缝问题。The paper combined with practical engineering,by means of finite element,the negative impact of the structure under the effect of temperature difference of a certain commercial complex PMSAP super-long basement structure was analyzed.Some corresponding measures such as concrete mix proportion optimization,post-cast strip setting,jump warehouse concrete pouring,high reinforcement ratio at large temperature stress places,smaller and closer layout of reinforcement and other measures were taken to solve the problem of super-long basement fracture.

关 键 词：超长地下室 有限元分析 温差效应
