高架桥作为城市内或城乡结合部的重要交通枢纽组成部分,高架桥与地面交通节点处时有车辆堵塞不畅发生,给墩高、长跨高架桥带来很多安全隐患.本文以某座四孔一联先简支后结构连续预制小箱梁为基础,对该既有桥梁进行结构安全验算,并给出计算体会和建议,以供桥梁设计同行业人员参考.

Viaduct is the major part of transportation hub of urban or semi-urban area. At the nodal point of viaduct and ground, sometimes the traffic is heavy, which brings safety risk to high pier and long-span viaduct. Based on a four-hole of a simply-supported and continuous precast box girder, the paper makes the checking computation of structural safety of existing bridges, and computing experience and recommendation, providing reference for bridge design industry personnel.
