| 摘 要： | 由于大跨径混凝土桥梁往往采用超静定的连续梁结构,温度效应在梁体的施工过程中甚至是成桥后的梁体结构中都是不容忽视的。对大跨径混凝土连续桥梁的施工过程中和成桥后温度对混凝土结构应力和变形影响进行研究是必要的。该文从客运专线铁路工程建设的应用实际出发,应用数值仿真模拟的方法,对连续梁温度效应进行研究探讨。其成果为今后客运专线...

| Abstract: | The temperature effect can not be ignored in the construction process of beam,especially in the beam structure after finished because of the long-span concrete bridge beam using the statically indeterminate continuous beam structure sometimes.It is necessary to study the influence of the temperature in the construction process of long-span concrete continuous beam and after finished on the concrete structure stress and deformation.From the application practice of the passenger transportation special line ra... |
