摘　　要：在进行大坝施工过程中采用碾压混凝土方式可以提升工程的施工进度、效率及经济效益,因此得到了广泛的应用。从大坝混凝土施工角度来看,大升层体积相对较大,所以在进行施工过程中容易出现混凝土水化热现象,要想有效避免此种情况应对施工温度进行严格控制,从而避免混凝土出现裂缝,确保施工质量。In the process of dam construction,the use of roller compacted concrete can improve the construction progress,efficiency and economic benefits of the project,so it has been widely used.From the perspective of dam concrete construction,the volume of large rising layer is relatively large,so the phenomenon of concrete hydration heat is easy to appear in the construction process.In order to effectively avoid this situation,the construction temperature should be strictly controlled,so as to avoid concrete cracks and ensure the construction quality.
