桥面平整度对连续梁桥动力响应的影响分析

Analysis on Influence of Bridge Level Degree on Dynamic Response of Continuous Beam Bridge

不同等级桥面平整度对连续梁桥各特征截面的动力响应有一定的影响。相关研究表明,桥面平整度是车辆对桥梁产生冲击的一个重要因素,现行桥梁规范中的冲击系数公式仅适用于桥面状况比较良好的情况。

The level degree of bridge in different rank has different influence on dynamic response of continuous beam bridge. As been proved, the level degree of bridge is one important factor leading to impaction on bridge. Formulas for impaction coefficient calculation in bridge criterion only fit for good condition of bridge.
