摘　　要：针对近年来发生的多起独住墩桥梁倾覆事件和各地普遍存在的支座脱空等问题,结合工程实例开展了独住墩桥梁受力探讨。首先对比了交通部征求意见的抗倾覆验算方案,对主要存在以上问题的曲线桥梁分析了梁体扭转、支座脱空的原因,并根据计算结果提出相应的加固措施,在实际加固处理工程中取得了良好的效果,可为其他类似工程提供参考。Due to the fact that many accidents of single - column pier bridge collapse have happened recently and bearing separation still exist in many places, the tolerance of single - column pier bridges is discussed combining with engineering project. Firstly the antidumping checking computation schemes proposed by Ministry of Communication are compared. The reasons of beam torsion, bearing separation are analyzed for the curve bridges which have the above problems, relevant reinforcement measures are proposed according to the results. Good effects are achieved through the process of actual consolidation handling, and it can provide reference for other relevant kind of operation.
