Abstract

Abstract: To increase the bearing capacity of Shizhu-Huanglong Bridge and enable it to meet the requirements of road-II load,the current technical state and bearing capacity of this bridge are evaluated through the full inspection,load test and finite element analysis.On this basis,the comprehensive technology is used in reinforcement design,such as reinforced concrete confining and high pressure grouting.After more than two years running,the good strengthening effect of this bridge has been proved.

Key words: stone arch bridge, strengthening, load test, bearing capacity, reinforced concrete confining, high pressure grouting

摘要： 为提高石柱黄龙大桥的承载能力,使其能满足公路-Ⅱ荷载等级的要求,通过全桥检查和荷载试验及有限元计算分析,对该桥目前的技术状况和承载能力进行了评价;在此基础上采用钢筋混凝土套箍、高压注浆等综合技术进行加固处理。该桥加固后经2^a多通车运行证明加固效果良好。
