【摘要】 桥梁是交通动脉的咽喉,它的运营状况关乎经济发展和人民生活。为了通过有效管理来保证桥梁的正常运营,桥梁管理系统应运而生。但现有桥梁管理系统通常只考虑桥梁的一般运营状态,对于诸多自然灾害尤其是地震灾害对桥梁安全的影响还缺乏相关的研究。为了能弥补这方面的缺陷,本文研究并开发了桥梁抗震管理系统。 本文介绍了桥梁管理系统(包括桥梁抗震管理系统)的研究现状和发展趋势;完成了桥梁抗震管理系统的总体设计,对系统的结构组成和各部分的主要功能进行了说明;建立了桥梁信息数据库,对桥梁信息表达方式、数据库访问和调用技术等进行了研究;详细介绍了信息管理、信息查询分析、状态评估预测、地理信息系统应用、数据输出等基本子系统的结构、功能和程序实现方式;综述了现有桥梁抗震能力分析的方法,参考现有桥梁管理系统和桥梁抗震理论提出了使用规范构造、规范计算和有限元计算对桥梁抗震能力进行评估的方法,并分别介绍了每种方法的具体内容、评估过程、评估结果及程序实现方式;结合GIS与数据库技术编写了桥梁抗震管理系统的程序,并通过实例应用验证了该程序的实用性和可靠性。 本文桥梁抗震管理系统实现了桥梁工程技术与信息技术的结合,为桥梁的抗震管理提供了一个科学有效的辅助技术手段。更多还原

【Abstract】 Bridges hold the key positions in transportation system, the performances of them are related to economic development and people’s lives. Bridge Management System (BMS) is created to ensure the bridge’s performance by effective management. BMS, however, considers the general condition, and does not consider the natural disaster actions, e.g. earthquakes. A Bridge Management System for Earthquakes (BMSE) was developed in this paper to remedy this shortage.The paper reviewed the art-of-state of the BMS (including BMSE), and a general idea was proposed for BMSE. The database of bridge information was developed, and the methods to manage the bridge information were suggested. Six subsystems of BMSE were introduced, and three methods were proposed to evaluate the damages of bridges under earthquakes by both the code method and FEM. The program of BMSE was developed with the GIS and Database technology, and an example was used to demonstrate the practicability and reliability of it.The BMSE realizes the combination of bridge engineering and information technology, and supplies an effective supplementary tool for bridge management under earthquakes.更多还原
