独柱墩连续弯梁桥抗倾覆稳定性验算方法及加固措施

摘要

In recent years,multiple whole -bridge overturning/collapse accidents happened to single column pier continuous bending beam bridges.This paper increases checking loads as appropriate on the basis of regular design loads in combination with project examples and in consideration of over -load factors to check and calculate the anti -overturning stability of in -service single column pier continuous bending beam bridges,and proposes reinforcing measures with targets.%近年来，独柱墩连续弯梁桥发生了多起桥梁整体倾覆坍塌事故。结合工程实例并考虑超载因素，在规范设计荷载基础上适当提高验算荷载，以检算在役独柱墩连续弯梁桥的抗倾覆稳定性，并有针对性地提出加固措施。
