独柱单支承上部结构抗倾覆稳定性验算分析及应用

摘要

According to the structural stress characteristics,analysis of single column single support beam bridge overturning failure characteris-tics,determined the calculation method is suitable for calculation of single column supported beam bridge of overturning stability,and combining with the example,made stability evaluation to a single column single support cast-in-place girder bridge,design and repair for the similar bridge reinforcement reference.%根据结构受力特点，分析了独柱单支承梁式桥倾覆破坏特征，据此制定出了适用于验算独柱支承梁式桥倾覆稳定性的计算方法，并结合实例对某座独柱单支承现浇梁桥进行了稳定性评价，可供同类桥梁的设计及维修加固参考。
