摘要
大体积混凝土在施工期间不可避免地会发生气温骤降.如果不注重表面保护,大体积混凝土表面极易开裂.通过对混凝土表面放热系数的计算、表面温度的计算以及混凝土表面保温计算原理的研究,为寒潮期间保温措施的采用提供了一定的参考,并计算了温度骤降对某典型坝段的影响.
During the construction period of mass concrete, the cold wave will be happened inevitably. If we do not pay attention to the surface protection, the surface would be cracked. Based on the concrete surface heat coefficient calculation, the surface temperature of the concrete surface, as well as the calculation of insulation on the principle of the cold wave; provide a certain amount of information to calculate insulation and effect of temperature drop of a typical section.
