大温差对兰新铁路混凝土结构温度应力的研究

兰新铁路第二双线(新疆段)沿线地区气候呈现大温差的特点,混凝土结构物必须采取保护措施,控制结构的温度应力。本文采用midas软件模拟计算混凝土桥墩的温度场和应力。通过与实际模型检测情况的对比,判断模型是否有效。

The climate along the double line of Lan- xin Railway( Xinjiang section) is characterized by large temperature difference. Protective measures must be taken to control the structure of the temperature stress by concrete structure.In this paper,the finite element analysis software Midas- civil was compiled to simulate the temperature and stress analysis. Contrast the finite element model with the actual model checking. Determine whether the model is effective.
