摘　　要：在水库大坝、电站厂房、船闸等水工建筑物的大体积混凝土浇筑过程中,容易产生裂缝。利用有限元分析方法,对大体积混凝土浇筑过程的温度场进行仿真分析,得出大体积混凝土浇筑过程温度场随时间的变化规律,并与实际浇筑过程中的混凝土温升监测结果进行对比,验证仿真分析的可行性,以进一步优化混凝土浇筑方法和温控措施。It is easy to produce crack during the pouring process of large volume concrete for hydraulic structures such as reservoir dam,power station workshop,ship lock,etc. Finite element analysis method is utilized for simulation analysis on the temperature field of mass concrete casting process. The change law of large volume concrete pouring process temperature with time is obtained. It is compared with the temperature temperature rise monitoring results in actual pouring process,thereby verifying the feasibility of simulation analysis,and further optimizing the concrete pouring methods and temperature control measures.
