【摘要】：交通运输关系国计民生和经济命脉,而大型桥梁则是确保交通能够畅通无阻的关键载体。为了保障大型桥梁结构的安全性、完整性、实用性和耐久性,结构健康监测技术应运而生。然而在实际情况中,尤其是在目前,城市化进程不断加快,城市快速路相互交错,组成了一张张交通路网,保证本区域的交通畅通。而大型桥梁健康监测系统并不能适应城市桥梁网络集群的特性,无法照搬到城市桥梁安全运营监测上来。针对这一现状,本文提出建立一个集群的网络式的城市桥梁安全运营监测网络系统,从整体的角度管理区域内的多座桥梁,并且能够在增加桥梁监测数量时做到不重新设计软件或做简单调整就能实现。能够同时在线了解区域内多座桥梁的实时运营情况,当一座桥梁出现问题时,可以及时查看对其他桥梁的影响,从而提前做好预防措施,防止安全事故的发生。围绕这个核心,本文主要做了以下工作：1.简要介绍了桥梁健康监测系统的概况,包括其发展历史和组成,在查阅了大量有关资料后,总结出了在构建城市桥梁安全运营监测网络系统中的几个关键性问题,包括传感器的优化布设、安全性评估、数据处理与软件架构以及数据传输与存储安全等问题。并着重研究了传感器的优化布设问题,包括其优化原则和优化方法,以及各种方法之间的对比,介绍了安全性评估的方法及国内外最新研究成果。2.重点介绍了城市桥梁安全运营监测网络软件系统各个子系统的详细设计,包括传感器感知层设计、桥梁结构安全与预警子系统设计、数据库子系统设计以及登录系统的设计。并就桥梁结构模态参数识别和损伤诊断以及有限元模型修正方法做了详细介绍；确定了软件编制的准则、流程,以及相关功能算法。3.利用MATLAB数据计算编程软件编制了其核心程序,即城市桥梁安全运营监测网络系统软件。该程序能够实现数据的采集、分析、模态识别、有限元模型修正以及预警报警功能；其页面友好,操作简单,易于管理和分析,可以为桥梁管理部门提供有效的管理工具。
[Abstract]:The relationship between transportation and economic lifeline and beneficial to the people's livelihood, large bridge is key to ensure the carrier transport can smoothly. In order to guarantee the safety of large bridge structure integrity, practicality and durability, as structural health monitoring technology. However, in the actual situation, especially in the current city, accelerating the process of city expressway. Interlaced, composed of a traffic network, ensure the regional traffic flow. And the large bridge health monitoring system can not adapt to the characteristics of city bridge network cluster, can not be moved to the bridge safety monitoring city. In view of this situation, this paper set up a cluster network of the city bridge safety operation monitoring the network system, from the overall perspective of bridge management within the region, and can not re design software or increase in the number of bridge monitoring Do a simple adjustment can be achieved. At the same time can real-time operation area bridges online understanding, when a bridge when there is a problem, you can see real-time effects on other bridges, so as to advance the prevention measures to prevent the occurrence of accidents. Around this core, this paper mainly do the following work: 1. are briefly introduced. Overview of bridge health monitoring system, including its development history and composition, by consulting a large number of relevant data, summarizes several key issues in the construction operation safety monitoring network system for city bridges, including the optimal placement of sensors, safety evaluation, data processing and software architecture and data transmission and storage security the problem. And it focuses on the optimization of sensor layout problems, including the optimization principle and method, and contrast between the various methods, the paper introduces the security evaluation The methods and the latest research results of.2. focuses on the detailed design of city bridge security operation monitoring network software subsystem, including sensor layer design, bridge structure safety and early warning subsystem design, subsystem design and the design of database login system. And elaborates the structural modal parameters identification and damage diagnosis and finite element model updating method; determine the software standards, processes, and related function of.3. algorithm using MATLAB data compiled the kernel program programming software, namely the city bridge monitoring network system security operation software. The program can realize the data acquisition, analysis, modal analysis, finite element model updating early warning and alarm function; the page is friendly, simple operation, easy management and analysis, can provide effective management for Bridge Management Department Tools.
