摘　　要：为及时准确辨识地铁深基坑风险信息、动态控制施工过程,针对现场管理中信息传递不及时、人为主观决策等问题,提出基于BIM的安全风险预警框架。以成都地铁深基坑为研究对象,创建基于BIM的深基坑风险预警模型。对基坑BIM信息模型进行模拟后,辨析项目隐含的风险信息,并进行4D模拟施工,对可能发生的风险作出预判并制订预防方案。最后界定施工事故险情及风险信息量化指标,根据T-S模糊神经网络融合模型确定风险预警值,在BIM界面中加以标识反馈,实现基坑安全风险立体控制。In order to timely and accurately identify the risk information of subway deep foundation excavation and dynamically control the construction process,the early warning of BIM safety risks is put forward.The risk early warning model of deep foundation excavation is established based on BIM.The information model of deep foundation excavation is simulated,the risk information implied is differentiated,the possible risks of the 4D simulation is predicted and prevented,the risk of construction accidents and risk information quantitative indicators is defined.According to the fusion model of T-S fuzzy neural network,the risk warning value is determined,the feedback is marked in the BIM interface,so as to realize the three-dimensional control of foundation excavation safety risk.
