车辆段上盖开发转换层温度应力分析

Temprature stress analysis of the conversion layer in above-underground development

综合考虑了各因素对温度荷载的影响,采用线性分布法计算作用在建筑物上的温度荷载,分析了车辆段上盖开发转换层从施工到正常使用全过程中可能受到的温度作用,制定了超长结构温度作用计算工况,以白云湖车辆段上盖开发项目为实例,给出最不利温度工况下的温度应力。计算结果表明,采用文中给出的超长上盖开发转换层结构温度作用计算模型,可为施工图设计起到指导作用。

The effect of the various factors on temperature load was comprehensively considered.The temperature load is determined by the linear distribution method.The temperature load from construction to the service stage of the whole process in above-underground development is analyzed and the working condition of calculation on super-long structure was determined.Taking the Baiyun Lake above-underground development as an example,the temperature stress in the worst work condition was presented.The results show that the model provided can play the role of guidane to construction drawing design.
