Abstract

A practical Bridge Management System has been developed by the author, which is referred to as the Japanese Bridge Management System (J-BMS) for existing concrete bridges. This paper introduces a newly developed bridge management system for the prestressed concrete (PC) bridges (J-BMS PC version) which is integrated with the PC bridge rating expert system (PC-BREX). The proposed system is able to predict the deterioration process of the existing PC bridge superstructure components as well as assess a broad array of optional corrective strategies. The system also has the capability to search and retrieve from a J-BMS database system (J-BMS DB), the necessary information, carry out suitable analyses to arrive at some recommendations that would help users to optimize their decisions based on engineering aspects, cost and economic issues and bridge management policies. A comparison of the results of applying the system to some actual in-service PC bridges with a special designed survey form to experts shows that optimal maintenance planning as well as bridge rating can be predicted accurately by using the system.
预应力混凝土桥梁寿命管理系统的开发与实际应用
作者开发了一个实用的桥梁管理系统,即日本既有混凝土桥梁管理系统(J-BMS)。本文介绍了一种新开发的预应力混凝土(PC)桥梁管理系统(J-BMS PC版),该系统与PC桥梁评级专家系统(PC-BREX)相结合。所提出的系统能够预测现有PC桥梁上部结构部件的退化过程,并评估一系列可选的纠正策略。该系统还能够从J-BMS数据库系统(J-BMS DB)中搜索和检索必要的信息,进行适当的分析,以得出一些建议,帮助用户根据工程方面、成本和经济问题以及桥梁管理政策优化决策。将该系统应用于一些实际在役PC桥的结果与专门设计的专家调查表进行比较表明,使用该系统可以准确预测最佳维修计划和桥梁等级。
