摘要
采用有限元法模拟乌东德水电站水垫塘边坡混凝土浇筑过程,就施工期考虑日照影响与不考虑日照影响2种情况进行温度仿真计算,对比分析了日照对水垫塘边坡混凝土的温度及温度应力影响。结果表明,在早龄期必须考虑日照对大体积混凝土表面拉应力产生的不利影响,需要采取必要的保温措施。
In this paper, the transient analysis type of FEM is applied to imitate the pouring process of side slope concrete in the plunge pool of Wudongde Hydropower Station. The effects on the temperature and thermal stress are compared under the solar radiation. The results indicate that insulation measures are obliged to be taken to deal with the adverse impacts on the surface pulling stress of early-age concrete structures caused by solar radiation.
