以江坪河水电站有压放空洞为例,利用ANSYS软件模拟1.0 m厚混凝土衬砌的夏季施工和运行过程,采用三维有限元法进行温度与温度应力的仿真计算,分析了不同浇筑温度方案的温度场和温度应力变化的一般规律,并进行了运行期不同过水水温的敏感性分析,由此推荐夏季施工的合理温控方案。仿真结果可为江坪河水电站1.0 m厚混凝土衬砌有压放空洞施工期和运行期的温控设计提供参考。
Taking the pressure pumped-out tunnel in Jiangpinghe Hydropower Station as an example, the construction and operation process of 1.0-m thick concrete lining in summer was simulated by ANSYS software. The three-dimensional finite element method was used to simulate the temperature and temperature stress. The temperature of different pouring temperature schemes Field and temperature stress changes in the general law, and carried out during the operation of different water temperature sensitivity of the sensitivity analysis, which recommended a reasonable summer temperature control program. The simulation results can provide reference for the temperature control design of the 1.0 m thick concrete lining of Jiangpinghe Hydropower Station during construction and operation.
