桥梁缺损状况分级的灰色聚类法

考虑到灰色聚类指标的重要程度不同,通过引入层次分析法确定的指标权重对灰色聚类分析进行了改进,提出了定权灰色聚类分析方法.运用该方法,依据〈公路养护技术规范〉选取桥梁分部构件评价指标,建立桥梁缺损状况评价模型,对路网中多种类型桥梁进行评价分级.通过实例分析证明了该方法的简便性与实用性.

The Grey Clustering Analysis of the Distress Condition Classification of Bridge

Thought the different importance of the grey clustering index,the grey clustering analysis is improved by introducing the index weight calculated by AHP(the Analytical Hierarchy Process).An evaluation model for the distress condition of bridge is built up by means of the weighted grey clustering analysis theory,in which the appraisal index are based on "Technical Specifications of Maintenance for Highway".The present model is used to evaluate the bridge stock in the network.The conclusion of an example is reasonable to some extend,it can prove the convenience and practicability of the model in this paper.
