摘要
针对独柱支承连续曲梁的预偏心距设计取值问题,考虑曲线桥梁的弯扭耦合作用,推出了两跨连续曲梁中支点预偏心距的计算公式,并对不同曲率半径的弯桥进行了结果比对,分析了误差来源,最后对公式进行了修正。
In this paper,according to the value in the pre-eccentric distance design of curved continuous girder with single-column supports,and considering the curved bridge coupling of bending and torsion,a formula of the pivots pre-eccentric distance has been derived to the two-span curved continuous girder.Comparison is made in different radius of the curved bridge,then analyzed the error,amended the formula.
