【摘要】：我国交通运输方式可分为三种:陆运、水运和空运。其中,通过桥梁进行运输属于陆运,且压力也是最大的,所以保证桥梁的安全使用可以缓解交通压力。目前,随着交通业的发展,人们对公路、桥梁的使用要求也越来越高,不仅要安全、快捷,行驶路面还要平整舒适。因此,为了使公路桥梁更好地为人们服务,不仅需要对公路桥梁的健康现状进行定期的分析检查,还必须及时地对不健康的桥梁进行维护,以提高桥梁的使用寿命。论文通过探讨人的健康,引出桥梁的健康探讨,对西北公路桥梁在设计、施工、使用过程中的各种影响因素进行分析,在此基础上对公路桥梁进行健康管理,并根据健康管理的实施步骤分析和设计了桥梁健康管理信息系统,实现了健康管理信息系统的部分功能。取得的研究成果和研究内容如下:(1)讨论了影响公路桥梁健康的主要因素,并从勘探设计、施工建设和使用维护这三个阶段对桥梁健康问题进行分析。结合现有资料、以及相关的评判数据,给出了健康等级评判标准。(2)健康管理是一个循环往复的管理过程。论文给出了桥梁健康管理的三个步骤,根据这三个步骤建立了公路桥梁健康管理信息系统的框架模型。健康管理信息系统包括三个部分,桥梁基本信息、桥梁健康评价以及桥梁健康恢复计划。文章对每个模块的功能都做出了基本的描述和详细的分析。关键是健康评价这一部分,先建立健康评价体系,确定健康评价指标,然后对各层次进行评价,最终汇总得到健康综合评价。另外制定桥梁健康恢复计划这一部分,根据评判结果,调查信息,制定相应的措施。(3)分析了桥梁健康管理信息系统应具备的功能,利用Visual Basic程序对桥梁健康管理信息系统所包含的功能进行了部分编程实现,使得此应用程序能为桥梁健康管理进行相关功能服务。(4)根据实际的西北公路桥梁的调查资料,利用桥梁信息系统对其进行健康评判,得出此桥梁的健康等级,制定相应的恢复计划,直观有效地对西北公路桥梁进行了健康管理。
[Abstract]:China can be divided into three modes of transportation: land, water and air transport. Among them, transportation by bridge belongs to land transportation, and the pressure is the greatest, so ensuring the safe use of bridge can alleviate traffic pressure. At present, with the development of traffic industry, people have higher and higher requirements for the use of roads and bridges. They not only want to be safe and fast, but also smooth and comfortable. Therefore, in order to make the highway bridge serve people better, it is necessary not only to analyze and check the health status of the highway bridge periodically, but also to maintain the unhealthy bridge in time in order to improve the service life of the bridge. Through the discussion of human health and the discussion of bridge health, the paper analyzes the influence factors in the design, construction and use of Northwest Highway Bridge, and on this basis carries on the health management of highway bridge. According to the implementation steps of health management, the bridge health management information system is analyzed and designed, and some functions of the health management information system are realized. The research results and contents are as follows: (1) the main factors affecting the health of highway bridges are discussed, and the health problems of bridges are analyzed from the three stages of exploration design, construction and maintenance. Combined with the existing data and the relevant evaluation data, the evaluation criteria of health grade are given. (2) Health management is a cyclic management process. The paper gives three steps of bridge health management, and establishes the frame model of highway bridge health management information system according to these three steps. The health management information system consists of three parts: bridge basic information, bridge health evaluation and bridge health recovery plan. The article has made the basic description and the detailed analysis to each module function. The key is the part of health evaluation. Firstly, the health evaluation system is established, and the health evaluation index is determined. Then, the comprehensive health evaluation is obtained by evaluating each level. In addition, this part of the bridge health recovery plan, according to the evaluation results, investigate the information, formulate the corresponding measures. (3) analyze the function of the bridge health management information system. The functions contained in the bridge health management information system are partly programmed by using Visual Basic program, which makes the application program serve the bridge health management. (4) according to the investigation data of the bridge in the Northwest Highway, By using the bridge information system to evaluate the health of the bridge, the health grade of the bridge is obtained, the corresponding recovery plan is worked out, and the health management of the bridge of the Northwest Highway is directly and effectively carried out.
