混凝土施工温度与裂缝预防措施

Discussion on Concrete Construction Temperature and Crack Prevention Measures

混凝土施工中产生裂缝有多种原因,通过对下车亭隧洞洞身衬砌混凝土进行温度量测与裂缝发展情况的观测,采取了裂缝预防措施。实践表明,控制施工温度及改善约束条件是防止裂缝产生行之有效的措施,为混凝土施工中预防裂缝的产生提供了借鉴和参考。

There are multiple reasons for crack in concrete construction.This paper puts forward the effective measures to prevent concrete crack by watching and comparing temperature measurements and the crack development of concrete in XiaJuTing tunnel hole body concrete.The practice indicated that controlling temperature in the construction and improving constraint condition is the effective control measures.The method in this paper provides reference and consulting for preventing crack from produce in concrete construction.
