【摘要】：桥梁建成以后,随着时间的推移、气候环境的变化,桥梁的性能退化速度越来越快,需要对桥梁不断地进行质量监控,从而保证在役桥梁更加经济节约地发挥其在道路运输行业中的价值。为了能够在桥梁建成以后对其进行及时有效的检测、合理地对桥梁的技术状况评估、提前预测桥梁技术状况、节约桥梁巩固和维修的成本、导出所需数据、制定合理的养护方案、有效地对桥梁进行管控,本论文研究并开发了一套科学规范的桥梁评定系统。该系统改善了目前大部分桥梁评定系统的算法通用性小、系统数据导出操作复杂、桥梁经常性检查数据录入繁琐等不足。论文首先比较了三种桥梁评定方法并选取最适合本课题数据的评定方法,根据实际情况对选定方法做了一定的补充改进;其次研究并使用实际数据对比了灰色系统和回归分析的预测模型,找出了结果最精确的桥梁预测模型;最后基于桥梁参数数据库对系统进行了功能需求分析,得出系统的功能主要包括对桥梁的基本信息管理、桥梁部件管理、桥梁病害管理、桥梁经常性检查、用户管理、权限组管理、导出桥梁的评价结果、病害信息、打印桥梁卡片、以及桥梁评定和预测功能等。经过综合比较,系统使用轻量级的Tomcat7服务器来减轻硬件的负载,选取Myeclipse为编程开发工具,采用基于web技术和SSH框架的B/S模式来实现本系统;并且利用FineReport报表设计器与数据库视图相结合开发本系统的报表功能。在实验环境下设计多个测试用例对系统的功能进行了白盒测试和黑盒测试,并完成了对系统性能的测试。测试结果表明系统在桥梁管理、桥梁评定方面功能完善,操作简便,与服务器通信稳定,能够完成桥梁的评定、打印评定结果,能够较为准确地预测未来技术状况走向,系统响应时间满足用户需求,具有较高的参考和使用价值。
[Abstract]:After the bridge is built, with the passage of time and the change of climate environment, the performance of the bridge degrades more and more quickly, so it is necessary to monitor the quality of the bridge continuously. In order to ensure that existing bridges more economically and economically play its value in the road transport industry. In order to be able to carry out timely and effective inspection after the bridge is completed, to evaluate the technical condition of the bridge reasonably, to predict the technical condition of the bridge in advance, to save the cost of bridge consolidation and maintenance, and to derive the necessary data, This paper studies and develops a set of scientific and normative bridge evaluation system. The system improves the common use of most bridge assessment systems, the complexity of system data export and the tedious input of bridge inspection data. Firstly, the paper compares three methods of bridge evaluation and selects the most suitable evaluation method for the data of this subject, and makes some supplementary improvements according to the actual situation. Secondly, the prediction model of grey system and regression analysis is compared with the actual data, and the most accurate bridge prediction model is found. Finally, the function requirement of the system is analyzed based on the bridge parameter database. The main functions of the system include the basic information management of the bridge, the management of bridge components, the management of bridge diseases, the regular inspection of bridges, the management of users, the management of authority groups, the derivation of the evaluation results of bridges, the information of diseases, the printing of bridge cards. And bridge evaluation and prediction function. After comprehensive comparison, the system uses lightweight Tomcat7 server to lighten the hardware load, selects Myeclipse as the programming development tool, and uses the B / S model based on web technology and SSH framework to realize the system. The report function of this system is developed by using FineReport report designer and database view. In this paper, several test cases are designed to test the function of the system in white box and black box, and the performance of the system is tested. The test results show that the system has perfect functions in bridge management, bridge evaluation, simple operation, stable communication with server, can complete bridge evaluation, print evaluation results, and can accurately predict the future technical situation. The response time of the system meets the needs of users and has high reference and use value.
