摘要
以经过加固后的深河大桥为工程背景,通过对该桥进行桥梁有限元模型分析和现场静动载试验,对桥梁加固后的承载能力和行车性能做出了评价,为该类桥梁的维修和养护提供参考。
Taking as an example the reinforced Shenhe Bridge,the paper carries out an analysis of finite element model and on-site tests of static and dynamic load and evaluates its load capacity and passing performance after reinforcement,which may be of reference for the maintenance of bridges of the same kind.
