摘　　要：对某公路桥段赤泥管道钢桥架的振动特性和现状进行检测,并调查钢桥架的实际荷载情况建立模型进行结构验算,经检测和验算后得到该钢桥架目前处于欠稳定状态,应对钢桥架进行加固处理。The paper carries out vibration characteristics and status detection of the steel-framed bridge with red-mud pipeline on the highway section,investigates the real loading conditions of the steel-framed bridge,establishes its model and makes structural checking. Through the detection and checking,it finds out that: the above-mentioned steel-framed bridge is unstable at present,which should be reinforced.
