偏心受压墩柱的有限元变形分析

Analysis on the finite element deform of eccentricity stressed piers

运用测量学、控制测量学的相关知识,求出偏心受压桥墩的偏心距;拟合出车辆在桥面上行驶时,轮胎滚动阻力对变形墩柱的影响公式,并进一步推出偏心墩的应力与应变公式,用有限元相关软件对模型进行模拟仿真,其结果为中心偏位过大墩柱的安全性提供了参考。

Using the related knowledge of metrology and control metrology, it deduces the linear eccentricity of eccentricity stressed piers, fits the formula of the affection of the rolling resistance of tyres to deformed piers when the vehicle going on the pavement of the bridges, and deduces the formula of stress and strain of eccentricity piers. It analogs and resembles the models by using the related software of finite element, and its results gives a reference to the safety of the big eccentricity piers.
