目前,大型工程中大体积混凝土施工一直沿用传统的计算方法和参数,然而计算结果与实测值却往往存在很悬殊差异。某工程便是典型的例子。该工程采用筏形基础,其厚度为1.8m,局部厚度达3m,整个底板面积近7000㎡,混凝土量1.2万m3,全部为C40P8混凝土。1温度计算值与实测值本工程基础 At present, the traditional calculation methods and parameters are always used in mass concrete construction in large-scale projects. However, the calculated results and measured values ​​are often very different. A project is a typical example. The project uses a raft foundation, the thickness of 1.8m, the local thickness of 3m, the entire floor area of ​​nearly 7000 square meters, the amount of concrete 12000 m3, all of C40P8 concrete. 1 temperature calculated value and the measured value of this project basis
