特殊重型车辆通过公路桥梁安全性评估及加固措施

Safety Assessment and Reinforcement Measures for Special Heavy Vehicles Passing Through Highway Bridges

以中国石油锦州石化反应器运输项目为背景,对于轴载或总重超过现行规范规定或超过桥梁限载的特殊重型车辆,需要通过公路桥梁的情况评估桥梁在特殊重型车辆作用下结构安全性。针对承载能力不能满足大型运输车辆安全通行的桥梁,提出桥梁临时加固措施。

Taking the reactor transportation project of PetroChina Jinzhou Petrochemical Company as the background,the structural safety of the bridge under the action of special heavy vehicles is evaluated when the axle load or total weight exceeds the stipulation of the current specification or the special heavy vehicles that exceed the bridge load limit need to pass through the highway bridges.In view of the bridge whose bearing capacity cannot meet the safety of large transport vehicles,the temporary reinforcement measure for the bridge is put forward.
