摘要
文中深入分析独柱墩桥梁倾覆事故原因,提出有效加固措施;通过统计国内事故案例情况,结合规范梳理事故桥梁破坏过程,总结钢盖梁加固、钢拉杆连接及钢管柱加固既有方法;针对城市净空不足、用地受限等问题,提出在特殊路段独柱墩桥梁建立监测及智能加固系统,以供参考.
Abstract
In order to analyse the reason of overturning accidents and propose effective reinforcement measures on single-column girder bridge,this paper counts domestic accident cases,and sorts out the process of bridge damage caused by accidents based on specifications,then summarizes existing reinforcement methods of steel bent cap,steel tie rod and steel pipe column.Under the condition of a limiting construction land and insufficient urban clearance,this study proposes to establish a monitoring and intelligent reinforcement system for single-column girder bridge.
