超长高架车站温度应力的影响研究

Study on the Influence of Temperature Stress on the Super Long Elevated Station

现在各大中城市轨道交通建设发展迅速,高架车站长度多为120m(6辆车编组),采用"站桥合一"的结构形式,导致其受温度荷载作用的影响较大。论文以实际工程为研究对象,采用Midas和盈建科软件对模型进行分析,通过温度荷载对构件配筋影响的情况分析,得出了不设变形缝的高架车站在控制温度应力方面的一些建议,为以后的城市轨道交通高架车站结构设计提供参考。

Now each big city rail transit construction develops rapidly, the length ofelevated station is 120m （six car marshalling） using ＂integrated station bridge structure, form a＂, which is affected bythe temperature load is large. This paper take the actual project as the research objeet, using Midas and profit analysis was carded out on the model o fthe sottware. The influence of temperature load on the reinforcement of the situation analysis, gives some suggestions of no deformation of elevated station joints in control of temperature stress, provide a reference for the design of city rail transit elevated station structure for the future.
