摘　　要：以宁波鄞州曼哈顿大厦项目塔楼处的不同厚度大体积混凝土底板为对象,进行了水化热的有限元模拟分析,制定了针对性的施工方案。通过将有限元模拟值与温度监测的实测值进行对比分析,总结了各类底板温度变化规律及对应施工措施,可作为后续项目的经验参考。Taking the mass concrete floor with different thickness at the tower of Manhattan Building in Yinzhou,Ningbo as the object,the finite element simulation analysis of hydration heat is carried out,and the corresponding construction scheme is formulated.Through the comparative analysis of the finite element simulation value and the measured value of temperature monitoring,the temperature change law and corresponding construction measures of all kinds of floor are summarized,which can be used as experience reference for follow-up projects.
