为进行城市桥梁养护与管理的深入研究,本文以北京市城市桥梁的现状和历年桥梁结构定期检测结果为研究背景,在定期检测的基础上,对北京市的城市桥梁养护与管理进行了剖析。分析结果表明:北京市近80%的桥梁为90年代建成,随着桥梁数量的进一步增加,今后一段时期内大部分桥梁的状态劣化衰退速度会呈现加快趋势,为应对旧桥养护高峰期的到来,必须尽快建立行之有效的养护和管理机制。本文探讨了基于结构定期检测的城市桥梁养护和管理机制,该思路、方法可供类似案例所参考。
In order to carry out an in-depth study on the maintenance and management of urban bridges, this paper analyzes the status quo of urban bridges in Beijing and the periodic test results of bridge structures over the years. Based on regular tests, the paper analyzes the urban bridge maintenance and management in Beijing. The analysis results show that nearly 80% of the bridges in Beijing were built in the 90s. With the further increase of the number of bridges, most of the bridge's deterioration of state degradation will accelerate in the next period. In response to the peak of the old bridge maintenance , An effective conservation and management mechanism must be established as soon as possible. This paper explores the urban bridge maintenance and management mechanism based on periodic structural testing. The idea and method are available for similar cases.
