摘要
在役的钢筋混凝土桥梁的可靠度分析是根据桥梁结构的现有状况及已有信息,并参考同类或类似结构的信息资料,采用适当的分析方法对其在服役基准期内的可靠度或失效概率进行评估,为合理利用桥梁提供依据。对已不满足现有需求的桥梁,应做出维修加固或拆除的决策,以避免重大事故的发生。
The reliability analysis of in-service reinforced concrete bridge is according to the present status and existing data of bridge structures, and reference to the structure of the same or similar information, with the appropriate analytical methods of estimation the reliability or failure probability for it in-service base period, which can provide the basis for rational utilization the bridge.The bridge which one no longer satisfied with the current needs, make the decisions of maintenance and reinforcement or demolition, to avoid a major accident.
