碾压混凝土上下层结合面上初始温度赋值方法研究

A Study on the Methods of Setting Initial Temperature on the Joint Face of Roller Compacted Concrete

本文首先对已有的多层板状结构温度场的解析解进行了分析，然后以此解析解为基础，比较了三种初值处理方法在各种浇筑温度与环境温度下的差别；最后推荐了碾压混凝土上下层结合面上温度初值赋值方法。

Theoretical solutions for multi layer thin plate structure's temperature field are given in the first part of this paper. Based on the solutions, three kinds of method which can set initial temperature on the joint face of roller compacted concrete under different placing conditions are compared in numerical calcu lation. At last, one of the methods is recommended.
