摘　　要：与传统基岩初温赋值方法作对比,采用施工过程仿真计算方法,提出了提前计算时刻空算基岩的初温赋值方法。计算结果表明,该方法可以更真实地反映不同浇筑季节下基岩对上部混凝土的约束作用,提高了仿真计算精度。Compared with the traditional method of setting initial temperature of the bedrock, a new method of setting initial temperature of the bedrock in advance using the simulation calculation method of construction process is proposed in this paper. The result indicates that it can more truly reflect constraint of the bedrock over the concrete placed on it and improve the simulation calculation accuracy.
