基于Web GIS的城市地铁施工监测信息管理系统研究

为确切反映建筑物、构筑物及基坑的实际变形程度和变形趋势，实现地铁信息化施工，需进行地铁施工变形测量，并对施工监测实现信息化管理。通过分析地铁施工特点、地铁施工监测的内容与监测精度，介绍了地铁施工监测信息管理及安全预警系统的设计过程，以及该系统用于城市轨道交通线路和车站土建工程施工的监测-作业-管理3方信息互联互动模式。系统具有地铁施工监测信息可视化管理、统计分析、安全预警和网上信息发布等功能，已应用于某城市地铁施工监测。

A study of monitoring information management system of metro construction based on Web GIS

In order to reflect the actual deformation degree and deformation trend of building, structure and foundation pit and to realize information construction of subway, it is necessary to carry out the deformation measurement of subway construction and information management of construction monitoring. The characteristics of metro construction, the contents of metro construction monitoring and monitoring accuracy are analyzed. The design process of metro construction monitoring information management and early warning system, and the interactive pattern of trilateral information monitoring-work-management system are introduced. The system has some functions, such as the visualization management of monitoring information, statistical analysis, early warning system, network information service, etc. This system has been used successfully in metro construction monitoring.
