摘要
根据隧洞混凝土温度场和温度应力的有限元计算原理,利用ABAQUS对实际施工过程进行模拟,得到混凝土温度场和温度应力场的分布规律,据此找出实际施工过程中的薄弱部位及加强监测部位,给出合理的温度监控布置方案。
Abstract： On the basis of the finite element calculation laws of the thermal fields and thermal stress fields, the actual construction process was simulated by ABAQUS. The regularities of distribution of the two fields mentioned above were obtained. And then the project of temperature mo- nitoring of subway tunnel concrete during the construction period was provided, which played a certain reference role in the construction of the subway tunnel concrete.
