摘要
水管冷却是混凝土坝施工中的主要温度控制措施,在混凝土坝施工过程仿真计算中如何考虑水管冷却效应是一个重要而又困难的问题,直接用三维有限元法求解,计算量太大;用近似解法,在某些情况下,计算精度可能不够。笔者提出了一套复合算法,计算效率高,计算精度也较好。
Pipe cooling is an important measure for controlling the temperature in concrete dams. How to consider the effect of pipe cooling in the computation simulating the construction process of concrete dams is an important but rather difficult problem. If the effect of pipe cooling is analysed directly by 3D finite element method, the amount of computation is too large, because very fine net work is required rear the pipe. Four compound methods are proposed in this paper to consider the effect of pipe cooling in the computation simulating the construction process. They are efficient and accurate for application in practical engineering problems.
