为了进一步提高地铁施工现场安全精细化智能管理水平，结合地铁施工现场实际，提出应当建设地铁施工安全风险远程网络系统。分析该系统功能需求，系统应实现人员、机械设备、环境、监测等信息的管理功能，以及不安全行为与状态评判、冲突风险分析、特殊天气风险分析、预测预警、隐患辨识与管理等功能。经分析，得出系统宜采用3D GIS技术和空间数据库技术。设计系统总体结构，探讨各项功能的实现方法，与现有可视化监控系统相比，其功能进一步拓展，更加智能化、集成化、可视化。

In order to further strengthen the safety and fine intelligent management level of Metro construction site, the author suggests that remote network system of safety risk in construction of Metro works should be established. The author analyzes the functional requirements of the system and points out that the system should achieve personnel, mechanical equipment, environmental monitoring and other information management functions, should realize evaluation of unsafe behavior and unsafe state, analysis on the risk of conflict, analysis of the special weather risk, forecasting and early warning, and identification and management of risks. Through analysis, the author believes that 3D GIS technology and spatial database technology should be used to develop the system. The author designs the overall structure of the system, and discusses the realization method of each function. Compared with existing visual monitoring system, the system has more expanded functions and is more intelligent, more integrated and more visualized. 
