超长混凝土结构温度应力及裂缝控制研究

Research on Temperature Stress and Crack Control of Ultra-Long Concrete Structure

对引起混凝土结构温度应力的温差进行了分析,并提出了温度应力与裂缝的控制措施,同时结合选取的工程案例,进行了验证探索,并进一步探讨了超长混凝土结构无缝设计与施工过程中的裂缝控制技术,以期为同行提供一定的参考。

In this paper,the temperature difference which causes the temperature stress of concrete structure is analyzed,and the control measures of temperature stress and crack are put forward.At the same time,combined with the selected engineering cases,the verification and exploration were carried out,and the crack control technology in the process of seamless design and construction of ultra-long concrete structure was further discussed,so as to provide some reference for the peers.
