地下工程施工监控地质地理信息系统研究

主要设计与实现了地下工程施工监控地质地理信息系统（MGGIS）。首先分析了系统特点、结构、具有的功能以及采用的平台和相关技术，定义了数据的获取和存储格式。然后在此基础上进行了3个功能独立的子系统的详细设计与实现，分别为工程计划显示子系统、平面时空效应子系统和断面图显示子系统。首次提出在RIA技术支持下，实现B/S架构下的工程地质地理信息系统；提出了反映随施工进度变化地下工程及环境空间信息的显示平台技术方案，充分反应了地下工程施工中空间信息具有时空效应的特点，适合地下工程安全风险管理的需要。该系统与同类型地理信息系统平台相比具有使用简单、交互性强、速度快等优点，研究成果已经在北京轨道交通工程安全风险监控系统和南京地铁工程安全风险监控系统等相关项目中得以应用。

Research of construction monitoring geology and geographic information system for underground engineering

We mainly made a design and implementation of construction monitoring geology and geographic information system for underground engineering (MGGIS). First, we analyze the characteristics, the structure，the function, the platform and the related technologies and define the access format for data to obtain and store. After that, we present a detailed design and implementation of three functional independent subsystems respectively: working processes project display, flat space-time effect and cross-section diagram subsystem. This is as far as we know the first proposition to use B/S framework geographic and geologic engineering information system for underground construction features via RIA technology. The scheme proposed can display the precise spatial information of changing environment in the construction of underground engineering，which is appropriate to the risk management of underground construction. With the advantage of being easy to use, interactive and fast running, our system is superior to old types of geographic and geologic information system. The achievement of our research has been used in Beijing Rail Transit Project Security Risk Monitoring System, Nanjing Metro Project Security Risk Monitoring System and other related projects.
