摘要
大体积混凝土表面温度受太阳辐射影响较大,直接导致混凝土内部温度场变化.为了精确描述混凝土温度场随日照的变化,结合太阳辐射与温升的关系,导出大体积混凝土在太阳辐射下表面温升的计算公式,同时求出表面温升对内部温度场影响的解析解,为分析大体积混凝土温度场提供理论依据.
The solar radiation has huge effect on .the surface temperature of large volume concrete. As a result, the internal temperature field of concrete will change with the surface temperature obviously. In order to describe the internal temperature field of concrete with the sun accurately, the temperature rising formula of concrete surface has been edueed through analysis of the relation between solar rediation and temperature rising. At the same time, the analytical resolution of the internal temperature field of concrete aroused by surface temperature has been obtained as well. It can provide the theory for the internal temperature field of concrete.
