CFST拱桥运营安全状态综合评估法应用研究

本文以张石高速公路石家庄北出口支线工程滹沱河特大桥为例,采用综合评估法和层次分析法建立评估模型,运用相应的方法确定权重,量化并确定指标层的评价指标评语,再利用变权原理考虑均衡化的影响,从而比较客观地对桥梁安全状态进行评估研究,为将来的桥梁安全监测、控制提供一定的基础参考价值。

Application of Comprehensive Assessment Method of CFST Arch Bridge Operation Safety Situation

This paper takes Shijiazhuang north exit Extension project Hutuohe Great Bridge of Zhangjiakou-Shijiazhuang Expressway as an example, uses comprehensive evaluation method and hierarchical analysis method to establish evaluation model, uses the appropriate method to determine the weights, quantify and determine the evaluation reviews of index layer, then uses variable weight principle to consider the impact of equalization, so as to objectively assess and research the bridge safety situation, provides a basic reference value for future bridge safety monitoring and control.
