基于BIM的泵站施工安全风险辨识与应用

Risk identification and application of pumping station construction safety based on BIM

从泵站工程事故成因出发,针对传统风险辨识方法及过程的不足,提出基于BIM的风险辨识方法.根据致险因素在BIM中辨识方法的不同将其分为静态与动态2种信息类型,设计提取并判断模型属性参数信息的流程,同时以三维可视化模型为基础,借助Visual Studio2017开发平台,利用C#对Revit进行二次开发,实现三维模型特定属性参数提取.通过规范条文分析法构建安全知识库,将提取的BIM属性参数与安全知识库中标准安全知识进行比对分析,从而实现对安全知识库中静态致险因素的自动辨识及可视化输出,同时可以利用SQL语言查询相关致险因素及预防措施,利用Navisworks实现动态致险因素的辨识.以某泵站洞口及脚手架辨识为例,分析了这种方法的可行性,研究对优化施工安全规划,弥补安全管理人员安全风险知识的不足具有重要的参考意义.

Starting from the cause of pumping station accidents,aiming at the shortcomings of traditional risk identification methods and processes,a BIM-based risk identification method was proposed.According to the different identification methods of risk factors in BIM,it was divided into static and dynamic information types,the process of extracting and judging model attribute parameter information was designed,at the same time,based on the three-dimensional visualization model,using Visual Studio 2017 development platform,and using C#for secondary development of Revit were implemented to extract the specific attribute parameters of the 3D model.The safety knowledge base was constructed through the standard article analysis method,and the extracted BIM attribute parameters were compared with the standard safety knowledge in the safety knowledge base,so as to realize the automatic identification and visual output of static risk factors in the safety knowledge base,at the same time,using SQL language to query related risk factors and preventive measures,and using Navisworks to realize the identification of dynamic risk factors.Taking the identification of the opening and scaffolding of a pumping station as an example,the feasibility of this method was analyzed,which is of important reference significance for optimizing construction safety planning and making up for the lack of safety risk knowledge of safety managers.
