高速公路路面养护管理系统开发和研究

在考虑当前路况的基础上，又考虑路龄的使用性能预测模型，预测的结果更为快速准确。探讨高等级公路道路养护管理决策系统和经济分析方法，提出了改进优劣系数法，该方法充分利用了专家经验知识，减小了决策误差。开发了高速公路路面养护管理辅助决策系统，建立高速公路基本数据库，由系统自动进行路面使用性能评价分析，并利用专家知识系统得出推荐养护方案，系统投入运行后反响良好。该养护管理系统的建立和实施进一步提高和改善了江苏省高等级公路的使用管理和养护管理模式，为高等级公路早日实现网级化系统管理奠定基础。

Development and Research on Maintenance Management System for Expressway Pavements

The pavement performance prediction including both the existing road condition and road age is presented, the prediction of pavement performance will be more quick and accurate. The maintenance decision and economic analysis method of high grade highway are discussed.The improved excellent-inferior coefficient method is presented which utilizes fully the expert's knowledge, the error is reduced and the maintenance decision obtained is more reasonable.The computer aided maintenance decision system of Expressway Pavement Management is developed. The databases of the expressway information are established, then the system evaluates the pavement performance automatically and recommends the maintenance scheme by expert knowledge. The establishment and the execution of the maintenance management system improve the mode of application management and maintenance management of high grade highway in Jiangsu Province and establish the development base of future network system management of high grade highway.
