摘要
温度效应对弯桥支座的受力影响较大,也直接影响支座的破坏。采用空间有限元程序建模,分析了温度效应下,桥梁圆曲线半径对支座受力的影响,以及桥下各支座受到的横向力的大小规律。计算结果表明支座受到横向力与桥梁圆曲线半径和温度有很大的关系。
This paper established the model adopted the spatial finite element program and analyzed the influence of bridge circular curve radius on the bearing force and the transverse force law of all the bearings under the bridge under the temperature effect. The calculated results showed that the bearing transverse force, the bridge circular curve radius and temperature had a great relationship.
