摘　　要：近年来,因车辆超载和偏载导致独柱墩连续弯桥垮塌事故频发,针对该类问题,对既有独柱墩桥进行安全评估与加固成为研究热点。以某城市立交匝道桥为例,采用Midas Civil有限元软件,对独柱墩连续弯桥抗倾覆稳定性进行验算分析,并结合桥梁结构特点,提出桥梁抗倾覆能力加固措施,以提高独柱墩弯桥的抗倾覆稳定性能,确保桥梁运营安全。In recent years,the collapse accidents of single-pier continuous curved bridges occur frequently due to vehicle overloading and eccentric load.In view of this kind of problem,safety assessment and reinforcement of existing single-pier bridges have become a research focus.Taking an on-ramp bridge of a city overpass as an example,Midas Civil finite element software is used to check and analyze the anti-overturning stability of a continuous curved bridge with single column pier.Combined with the structural characteristics of the bridge,measures to strengthen the anti-overturning capacity of the bridge are proposed to improve the anti-overturning stability of the bridge with single column pier and ensure the safety of bridge operation.
