摘　　要：某研发中心一期工程地下室为超长混凝土结构,本工程通过温度应力计算对结构在温度作用下产生的变形和内力有一个整体的、趋势上的把握,明确结构上温度应力集中的部位,从而有的放矢采取构造措施,合理设置后浇带和温度构造钢筋,采用补偿收缩混凝土及在环境温差、材料、混凝土生产技术和施工方面做好控制,缩短了工期,降低了工程造价,避免有害裂缝出现,实现了超长地下室结构的无缝设计,可供类似工程参考。The basement of a research and development center project is the long concrete structure, The project is calculated by temperature stress, under the action of temperature, the internal force and deformation of the concrete has the overall analyzed, clear the temperature stress concentration of the site, take constructive measures, set the post-pouring zone and strengthen measures, shorten the construction period, reduced the project cost, and avoid the emergence of cracks. To achieve a long basement structure of the seamless design for later similar engineering reference.

关 键 词：超长混凝土结构 裂缝控制 温度效应分析 后浇带
