摘要
根据洪口水电站碾压混凝土大坝的施工进度,进行了大坝施工期和运行期的温度场和应力场的仿真计算,讨论了坝体设置诱导缝和永久横缝的优劣,分析可能产生裂缝的原因及提出相应的温控防裂措施。
Based on the scheduled construction progress of the RCC dam in Hongkou hydropower station, numerical simulation is used to simulate and calculate temperature field and stress field during construction and operation stages of the RCC dam. The qualities of induced joints and permanent transverse joints laid at the RCC dam are discussed. Furthermore, simulation calculation is done in order to analyze the possibility of cracks and to extract the methods of temperature control and crack prevention.
