摘　　要：山西省境内大件运输车辆通行数量多、通行范围广,存在大件运输车辆通行独柱墩桥梁的可能性,但现阶段对桥梁结构抗倾覆稳定性研究存在空白。以某案例为背景,分析大件运输车辆偏离桥梁中线行驶对桥梁结构抗倾覆性能的影响。结果表明,即使大件运输车辆偏离桥梁中线距离较小时,对结构抗倾覆稳定性影响也较大,大件运输车辆需严格居中行驶,同时进行交通管制以保障通行安全。With the large number and wide range of large transport vehicles in Shanxi Province,large transport vehicles may pass through single-column pier bridges,however,there are gaps in the study on the overturning stability of the bridge structure.Based on actual practice,this paper analyzed the influence of large transport vehicles passing off the bridge centerline on the overturning stability of the bridge structure.The results showed that even if the distance of the large transport vehicle deviating from the bridge centerline was small,it greatly impacted the structure's overturning stability.Large transport vehicles should pass the bridge along the centerline strictly,and supplemented by traffic control to ensure traffic safety.
