摘要
表面保护是防止大体积混凝土表面温度裂缝的有效措施。本文论述了表面保护的计算分析方法,着重阐述了温度应力分析法的计算内容和步骤,并根据应力计算结果对表面保护标准和时间以及保护材料和层厚的选定等,作了具体的分析。
Surface protection is one of the effective measures for surface crack prevention. of mass concrete. This paper deals with the calculation analysis method of surface protection, with the emphasis on the main factors and steps of temperature stress calculation. Meanwhile, according to the results of stress calculation, the standard, time, and material of protection are also studied.
