Recently, due to such factors as the increase in traffic volume, the increase in the weights of vehicles and the structural aging, many highway bridges have seriously deteriorated over the years in many advanced countries. In Japan, one report shows that in about 10 years from now, around 2010, the ratio of the bridges which will reach 50 years of age will be about 35% since many highway bridges have been constructed through the national highway networks' project launched around 1955. Thus, it is essential that those bridges should be repaired or strengthened depending on the seriousness of their deterioration. Despite the problem, since the limited, it is necessary for the funds to be split equally for both maintaining the deteriorated bridges and constructing the new ones. For this reason, the necessity of developing a practical bridge management system has been pointed out in Japan, because the maintenance of existing bridges has become major social concern. The goal of this system … More is to assist the decision-makers and the administration in doing their job.This study attempted to develop a decision support system for rehabilitation strategies of existing concrete bridges based on life cycle analysis (newly developed Bridge Management System(J-BMS) integrated with the Concrete Bridge Rating Expert System). This proposed system is able to not only evaluate the serviceability of existing bridge members, but also offer some strategies based on a combination of maintenance cost minimization and quality maximization approach. For solving this optimization problem, the Genetic Algorithms were adopted. By applying these algorithms to the optimization problem, the Genetic Algorithms were adopted. By applying these algorithms to the optimization problem, the approximation optimal solution (rehabilitation strategy) could be quickly found. Moreover, applications to some existing concrete bridges were presented so as to demonstrate the suitability of proposed bridge management system. As a result, it was verified that this proposed system is able to estimate the deterioration of bridge members and present various rehabilitation strategies. Less

近年来，由于交通量的增加、车辆重量的增加和结构老化等因素，许多先进国家的许多公路桥梁多年来已经严重老化。在日本，一份报告显示，从现在开始的大约10年内，大约2010年，达到50岁的桥梁的比例将达到35%左右，因为许多公路桥梁是通过1955年左右启动的国家公路网项目建造的。因此，至关重要的是，这些桥梁应根据其损坏的严重程度予以修复或加固。尽管存在这个问题，但由于资金有限，有必要将资金平均分配用于维修损坏的桥梁和建造新的桥梁。因此，在日本，开发实用的桥梁管理系统的必要性已经被指出，因为现有桥梁的维护已经成为主要的社会关注。这个系统的目标是 ...更多信息 本研究试图开发一个基于生命周期分析的既有混凝土桥梁修复策略决策支持系统（结合混凝土桥梁评级专家系统的桥梁管理系统J-BMS）。该系统不仅能够评估现有桥梁构件的使用性能，而且还提供了一些策略的基础上相结合的维护成本最小化和质量最大化的方法。采用遗传算法求解该优化问题。将这些算法应用到优化问题中，采用遗传算法。通过将这些算法应用于优化问题，可以快速找到近似最优解（修复策略），并将其应用于一些既有混凝土桥梁，以证明所提出的桥梁管理系统的适用性。其结果是，它被验证，该系统能够估计桥梁构件的恶化，并提出各种修复策略。少
