摘要
分析了混凝土徐变对混凝土温度应力的影响,提出了温度和收缩作用下,徐变应力的计算方法,通过工程实例,在采取综合控制裂缝措施的同时,提出了与实际较吻合的徐变收缩公式,对大面积混凝土梁板结构不设温度缝来解决温度应力问题的理论分析和工程设计与施工提供了有益的借鉴。
Analying the temperature stress. We provide the method of how to calculate the stress of creep and analyze the influence created by creep. Through some project examples, we were not only adopt synthesizes the anti-seam measure but also pride the formula of creep and shrinkage which be same as the true. That would benefit the designers and constructors when they solve the temperature stress without any seams on large area concrete structure.
