摘要
既有公路梁、拱桥为公路桥梁常见桥型。对于高地震烈度区的桥梁养护管理工作,既有桥梁抗震加固是保证桥梁正常运营的工作重点之一。在分析桥梁震害特征的基础上,提出既有公路梁、拱桥抗震的加固对策,具有重要意义。
The existing highway beam and arch bridge are the common type among highway bridge. For the management of the bridges in earthquake hazardous areas, anti-seismic reinforcement is one of the focuses of the bridge maintenances. Based on the features of the seismic damage to beam and arch bridges, several reinforcement measures are proposed, which is significant.
