【摘要】 目前我国铁路建设进入高速发展时期,铁路隧道设计速度快,技术标准高。为实现隧道在施工过程中结构的稳定与安全,确保运营质量,需对隧道线下工程以及周边建筑物安全进行动态观测。传统的监测方法周期长、数据多。为了弥补传统数据处理方法的不足,研发隧道施工安全监测系统,对于保证隧道施工行安全和提高隧道运营经济效益具有重要意义。基于以上考虑,论文把WebGIS的概念引入到铁路隧道监测信息管理中,实现了监测信息可视化和网络化管理。主要研究内容如下：(1)首先介绍了监测工程概况、监测对象和监测基准,监测数据采集,完成了系统用例分析。此外,对比了当前主流WebGIS开发平台及平台的性能特点。深入分析了隧道施工安全监测系统的功能需求、系统实现目标,从而建立了系统功能模型。(2)论文从系统设计原则与设计目标出发,对总体结构设计、系统功能模块设计、数据库设计等方面深入探讨了系统的设计方案。并根据系统的开发需要设计JSON数据格式转换和矢量地图制作相关技术方案。(3)实现了隧道施工安全监测系统,实现对地图的基本操作,并能够方便的操作监测数据,包括数据存储、查询、修改、删除。系统实现了对监测点的布置和监测信息展示,在用户导入各监测点数据的时候系统依据监测基准,自动的计算出报警和预警的监测点,并在地图上以醒目的颜色展示出来,以实现预、报警功能并且生成相应的监测曲线,使用户及时了解到监测对象的形变或沉降的程度。更多还原

【Abstract】 At present. Chinese railway construction is entering a period of rapid development, and speed railway tunnel needs high technical standards.In order to ensure stability and security of railway tunnel structure, we need dynamic observation for tunnels under the project and the surrounding buildings’ safety. Traditional monitoring methods have a long period and massive data. To solve the traditional data processing problem, research and development tunnel construction safety monitoring system, which have great significance for ensuring the tunnel construction safety and enhance tunnel operation benefit.Based on the above considerations, the thesis introduces the concept of the WebGIS into the railway tunnel monitoring information management, information visualization, and implement the monitoring and network management. The main contents as follows:(1) The thesis firstly introduces the monitoring of project survey, monitoring object and benchmarks for monitoring, analyzing business processes of the system and design the function module. In addition, compared to the current mainstream development WebGIS platform’s performance. Thesis analysis tunnel construction safety monitoring system functional requirement, system goals, and established the system function model.(2) The thesis secondly introduced the system design principles and design objective, according to the requirement, design the overall structural,system function module,relative database, and design JSON data format conversion methods and vector map-making technology solutions.(3) The tunnel construction safety monitoring system, implement map basic operations and manager monitoring data, including data storage, query, modify, deleting. System implement monitoring points layout and monitoring information displayed.When monitoring data import database.the system according to setting the alarm and warning value automatically calculate the alarm and warning of the point, and display significant color to representive the monitoring point state.In order to directly reflect monitoring point state,the system provides appropriate monitoring curve painting function,allowing users to understand the dynamic monitoring of the deformation of the object and settlement levels.更多还原
