摘要
以专业有限元计算软件Midas Civil为平台,在大风、干旱、大温差环境下,对大体积高性能混凝土进行水化热模拟分析、计算,寻求大体积混凝土水化热温度分布存在的规律,并提出了防止水化热温度梯度而导致的墩身早期开裂的有效工程措施,为以后的设计与施工提供一定的参考。
Based on the platform of professional finite element calculation software Midas Civil,in the environment of strong wind,drought and big temperature difference,the hydration temperature of the mass concrete of high performance was simulated,analyzed and calculated,and the distribution rules of hydration heat of mass concrete were explored,and the effective engineering measures for preventing early pier body cracking resulting from temperature gradient of hydration heat were put forward,which can be of certain reference for future design and construction.
