大体积混凝土承台水化热监测及数值分析

摘要

对某特大桥承台按照一次浇筑施工的方法运用Midas/Civil进行了数值分析,进行了影响水化热的参数敏感性研究,得出施工中参数的选择原则,对大体积混凝土的水化热控制具有一定的参考价值。%The paper undertakes the numeric analysis of the bearing platform along some super-large bridge by adopting Midas/Civil according to the single casting construction method,undertakes the research on the sensibility of the parameter which influence the hydration heat,and concludes the selective principle for the parameter in the construction,so as to have some reference value for the hydration heat control of the large concrete.
