摘要
应用精度较高的水管冷却混凝土温度场离散迭代算法对某混凝土重力坝进行全坝段仿真计算,结果揭示了坝体准稳定温度场、坝体温度和应力变化规律。提出的温控防裂措施合理可行、效果明显,对设计和施工具有重要的参考价值。
The explicit iterative algorithm for pipe cooling concrete temperature field has high precision, which is applied in the whole section simulation of a concrete gravity dam. The results show the dam quasi steady temperature field, dam temperature and stress duration. Reasonable and feasible temperature control and crack preventing measures are provided, which are of important reference to designing and construction.
