摘要
由于皂市大坝工程进度滞后较多,为了按时完成工期,增设了2台门机浇注大坝。对皂市大坝溢流坝段施工期混凝土的温度进行了仿真计算,得出了坝体温度场分布及其随时间的变化规律。从温控的角度,为皂市大坝高温季节采用三级配混凝土泵浇筑溢流坝段的可行性提供了可靠的参考依据。采用三级混凝土泵浇注皂市大坝混凝土是皂市大坝工程能按时安全竣工的决定性条件。同时为其他工程在混凝土浇注过程中采用三级配混凝土泵提供了参考。
Increasing two cranes to complete the Zaoshi RCC dam in time because the time for the project was delayed. To carry out the simulation calculation of the temperature field of Zaoshi RCC dam during construction period, the change laws of temperature field with time and their distributions are suggested. Whereby providing the reliable basis of the dam cast and for corresponding tempera- ture control measures during the overfall dam construction in high temperature with three level pumpcrete machines. It is a critical condition to complete the Zaoshi RCC dam with three level pumpcrete machines. There is a consult for other project the same time.
