连续太阳辐射影响下混凝土温度仿真计算连续太阳辐射影响下混凝土温度仿真计算 摘要:高温季节浇筑混凝土时,气温柔太阳辐射对混凝土浇筑后温度影响大
模拟了某工程非溢流坝段碾压混凝土的浇筑过程,就有无考虑连续太阳辐射影响下、不同持续太阳辐射时间下混凝土表面点与内部点温度过程进行了仿真计算
结果表明:连续太阳辐射对混凝土的影响深度是有限的;由太阳辐射引起混凝土表面最高温度升高值前期增长幅度大后期增长小
Abstract: high temperature season during the pouring of concrete, temperature and solar radiation effect on the temperature of concrete
Simulation of the construction process of an engineering non-overflow dam section of roller compacted concrete, there is no consider the influence of continuous sun radiation, solar radiation under different time points on the surface of concrete and internal temperature process simulation calculation
The results show that: the influence of solar radiation on concrete depth is limited by the maximum temperature; concrete surface increased value in early growt
