地铁施工安全受工程地质条件、当前施工进度、周边环境等多因素综合影响。通过构建可视化仪表盘，基于地铁工程三维实体模型，动态显示在上述各影响因素耦合作用下工程的安全状态，支持作业风险和危险构件及其影响区域实时预警和控制，准确识别工程的最危险部位、风险区域分布、等级状态等，为现场安全管理提供决策支持。

Metro construction safety is affected by many factors,such as engineering geology condition, nearby buildings and engineering design plan, etc.This paper proposes a dashboard tool based on 3D models to control the safety of metro construction. Risk activities and current safety status of the construction can be identified and shown via this dashboard. It can help project managers to figure out the safety status of the construction and risk activities intuitively and timely which improves safety management in metro construction.
