既有独柱墩桥梁交通流量分析及其工程应用

Traffic Flow Analysis and Engineering Application of Existing Bridge with Single Pier

独柱墩桥梁在偏载及重载车辆作用下,易产生横向失稳现象。对于既有独柱墩桥梁,如何运用科学手段进行抗倾覆评估,是桥梁管养人员需要关注的问题。文中提出了一种基于交通流量分析对既有独柱墩桥梁进行运营安全评估的方法,可与理论计算相结合,从桥梁实际运营状况出发,对桥梁进行科学管养。

Single pier bridge is prone to lateral instability under partial load and heavy load vehicles. For existing single-pier Bridges, how to use scientific means to evaluate the anti-overturning is a problem that bridge stewards need to pay attention to. In this paper, a method based on traffic flow analysis is proposed to evaluate the operation safety of existing single-pier Bridges, which can be combined with theoretical calculation and scientifically manage the bridge from the actual operation condition of the bridge.
