【摘要】：目前我国许多大城市已经拥有地铁,地铁在缓解城市交通压力方面发挥着重大的作用。地铁隧道在建设或建成后,由于地质条件、地面建筑物开发等诸多因素导致隧道结构发生沉降和偏移等变形。如果不能对其进行自动的、连续的、长期的变形监测,则很难及时发现险情,将会对隧道安全造成严重的威胁。本文在分析总结地铁隧道变形监测技术的基础上,通过学习和吸收国内外先进的地铁隧道自动化监测系统的设计理念与技术成果,明确了地铁隧道自动化监测系统的建设目标,分析了系统的具体功能需求,完成了系统总体框架和详细的功能设计。利用面向对象的程序语言Visual Basic 6.0和Microsoft SQL Server数据库进行系统开发。根据系统涉及的数据类型,对数据结构表进行了详细的设计并实现系统与数据库之间的连接。重点对地铁隧道自动化监测系统关键技术进行了研究和探讨,包括Geo COM接口技术、多重差分改正技术和远程数据通讯技术。最后对设计的地铁隧道自动化监测系统相关功能加以实现,并结合实际的地铁隧道变形监测项目对系统进行测试。在系统设计过程中,基于Geo COM接口技术对测量机器人进行二次开发,通过调用Geo COM函数包中的功能函数,实现系统与测量机器人远程连接、仪器参数具体配置和相应的测量功能;在数据处理方面,根据监测数据的误差来源,深入研究了多重实时差分改正技术,消除或减弱了气象因素带来的误差影响,大大地提高系统监测的精度;深入探讨了有线和无线两种远程通讯技术,经过对比分析,系统采用GPRS调制解调器无线网络方式进行远程数据交换,成功实现了监测系统高度自动化和智能化的设计目标。最后通过实例应用表明,该系统可以高效、准确、实时地完成无人值守的隧道自动变形监测任务,并取得了较好的监测效果,达到了系统最初的设计目标。这对观测周期长、观测环境恶劣以及重复性强的变形监测工程来说具有重要的现实意义。
[Abstract]:At present, many big cities in our country already have the subway, the subway plays an important role in relieving the urban traffic pressure. After the subway tunnel is built or completed, due to the geological conditions. Ground building development and other factors lead to deformation of tunnel structure, such as settlement and displacement. If it can not be automatic, continuous, long-term deformation monitoring, it is difficult to find the danger in time. This paper analyzes and summarizes the deformation monitoring technology of subway tunnel. By studying and absorbing the design ideas and technical achievements of the advanced subway tunnel automation monitoring system at home and abroad, this paper clarifies the construction goal of the subway tunnel automation monitoring system, and analyzes the specific functional requirements of the system. The overall framework of the system and the detailed functional design are completed. Using the object-oriented programming languages Visual Basic 6.0 and Microsoft SQL. Server database for system development. According to the data types involved in the system. The data structure table is designed in detail and the connection between system and database is realized. The key technology of subway tunnel automation monitoring system is studied and discussed, including Geo COM interface technology. Multiple differential correction technology and remote data communication technology. Finally, the design of subway tunnel automation monitoring system related functions are realized. And combined with the actual subway tunnel deformation monitoring project to test the system. In the system design process, based on the Geo COM interface technology to the measurement robot secondary development. By calling the function function in the Geo COM function package, the remote connection between the system and the measuring robot, the specific configuration of the instrument parameters and the corresponding measuring function are realized. In the aspect of data processing, according to the error source of monitoring data, the multiplex real-time differential correction technology is deeply studied, which eliminates or weakens the error effect brought by meteorological factors, and greatly improves the accuracy of system monitoring. Two remote communication technologies, wired and wireless, are discussed in depth. Through comparison and analysis, the system adopts the wireless network mode of GPRS modem to exchange remote data. The high automation and intelligent design goal of the monitoring system has been successfully realized. Finally, the application of the system shows that the system can efficiently, accurately and realtime complete the automatic deformation monitoring task of the unattended tunnel. A good monitoring effect has been obtained and the initial design goal of the system has been achieved, which has important practical significance for the deformation monitoring engineering with long observation period, bad observation environment and strong repeatability.
