摘要
基于博弈论组合赋权法研究高速公路桥梁综合评价方法,以期提高桥梁管养水平.提出路网桥梁综合评价的指标:路线交通量、桥梁技术状况评分、基础数据(桥梁跨径、使用寿命)、技术状况预测数据.桥梁技术状况评价预测采用灰色神经网络模型,得到在不考虑养护情况下桥梁自然退化的预测趋势.通过湖北省内某段高速公路的算例,验证了综合评价方法和预测模型的可行性,得到该段桥梁综合评价结果.
Abstract
Based on game theory,the comprehensive evaluation method of highway bridges is studied in order to improve the level of bridge management and maintenance.The indicators for comprehensive evaluation of road network bridges is proposed:route traffic volume,bridge technical condition rating,basic data(bridge span,service life),and technical condition prediction data.The Grey neural network model is used to evaluate and predict the technical condition of bridges,and the predicted trend of natural degradation of bridges without considering maintenance is obtained.The feasibility of the comprehensive evaluation method and prediction model are verified through a calculation example of a certain section of an expressway in Hubei Province,and the comprehensive evaluation results of the bridge section are obtained.
