摘要
根据碾压混凝土重力坝的施工特点,提出用国际通用大型有限元软件Ansys进行大坝施工期温度场仿真,并介绍了实现过程。典型碾压混凝土重力坝的施工期温度场仿真计算结果表明,浇筑温度及外界气温对坝体温度均有显著影响,碾压混凝土自然降温速度缓慢。
In this paper, Ansys software, a world wide popular common software used in finiteelement analysis, is suggested to simulate the temperature field of roller compacted concrete gravity dam during construction. According to a scheduled timetable of construction, temperature fields of a typical RCC gravity dam within construction period under several different construction conditions are calculated by simulating the layer constructing of the dam. The temperatures of placed RCC and air effect heavily on the temperature field of dam.
