摘要
对于弯桥尤其是小半径弯桥,其各主梁的受力情况较直线梁桥复杂。一些适合直线梁桥横向分布的计算方法也不一定适用于曲线梁桥。通过运用梁格法与偏心压力法来计算分析一简化T型梁桥模型,并对其所得横向分布系数的结果进行比较,得出各方法分析所得的荷载横向分布特点,对实际工程提供参考。
For curved bridge,especially for the small radius one,the stress of its main beam is more complex than the straight bridge's.Some calculation method of transverse distribution of the straight bridge may not apply to the curved girder bridge.Grillage method and the eccentric compression method are used to calculate and analysis a simplified T bridge model,and comparing the results of transverse distribution coefficient,to get the characteristics of the two methods.The actual project is provides the reference.
