摘　　要：近年来,随着大型钢结构间冷塔的陆续建设,其基础的受力特点也备受关注。以某国内在建的大型钢结构间冷塔环基为例,基于有限元分析技术分析了环基浅埋下的温度分布以及温度受力,指出了环基浅埋情况下主要受温度荷载影响,提出了环基温度分布分析方法,阐明了环基在温度作用下的受力主要受约束刚度的影响,为钢结构间冷塔环基设计提供参考。In recent years,with the successive construction of large-scale steel cooling towers,the stress characteristics of the foundations have also attracted much attention.Based on the FEA technology,the temperature distribution and temperature force under shallow burial of the ring base are analyzed for a steel cooling tower.It is pointed out that the ring base is mainly affected by temperature load.A method for analyzing the temperature distribution of ring base is proposed.Furthermore,it is clarified that the force of ring base under the action of temperature is mainly affected by the restraint stiffness,which can provide reference for engineers and technicians.
