基于BIM的北京地铁19号线平安里站施工风险巡视过程控制研究

为有效解决工程风险巡视效率低下、协同度低、主观能动性差的弊端，加强风险巡视的过程控制，充分利用BIM技术的可视化和信息集成化特点，同时保证施工过程风险管控的有效性和可追溯性，依托在建北京地铁19号线平安里站对施工风险巡视过程控制进行研究。研究基于自主研发的风险巡视APP和搭建的BIM-GIS三维场景，首先，通过现场定位和虚拟仿真的手段实现排查位置和排查信息的记录；其次，对排查信息设置风险过滤条件；最后，对风险信息进行集成管理。研究得出： 基于BIM的风险管理可以控制风险巡视过程，快速有效地分类整理并推送风险集成信息，通过BIM可视化和信息集成化的手段可以有效地控制整个管理流程，提高风险识别能力。

Construction Risk Inspection Process Control of Ping′anli Station on  Beijing Metro Line No. 19 Based on BIM Technology

The project risk inspection is always characterized by low efficiency, low coordination and poor subjective initiative. Hence, in order to strengthen the process control of risk inspection, make full use of the visualization and information integration characteristics of BIM technology, and ensure the effectiveness and traceability of risk management and control in construction process, the process control of construction risk inspection of Ping′anli Station on Beijing Metro Line No. 19 under construction is studied. The risk inspection APP and BIM GIS three dimensional scene based on independent research and development are studied. Firstly, the location and information of investigation are recorded by means of on site positioning and virtual simulation; secondly, the risk filtering conditions are set for investigation information; finally, the risk information is integrated and managed. It is concluded that the risk management based on BIM can control the process of risk inspection, sort out and push risk integration information quickly and effectively, and control the whole management process effectively by means of BIM visualization and information integration, so as to improve the risk identification capacity.
