［摘要］根据工程实例，提出了凹槽式伸缩缝结构设计。整体结构划分为3个单元，每个结构单元内部采用了凹槽式伸缩缝的处理，并对该措施进行了一定的理论分析与构造研究。分析表明，凹槽式伸缩缝的设置，既保证了单元的侧向刚度，又降低了温度应力，获得了良好的设计效果。

Abstract:The control joint structure was presented based on the concrete project. The whole structure was divided into 3 structural elements, and the control joint was used within each element. Both theoretical analysis and configuration research were conducted. It is found that the control joint structure can provide high lateral stiffness and reduce the temperature stress effectively.

Keywords:control joint; super long structure; temperature stress
