基于BIM实施与结构有限元分析的城市轨道交通智慧监测技术研究

Research on Intelligent Monitoring Technology of Urban Rail Transit Based on BIM Implementation and Structural Finite Element Analysis

本文将BIM技术和FEA分析技术相结合,通过城市轨道交通车站临近既有铁路的施工过程为实施案例,对地铁车站基坑开挖进行有限元分析,并引入BIM集成平台,实现了BIM管理平台数据格式转化与邻近既有铁路的深基坑施工安全风险评估模型的嵌入,最终建立起动态可视的施工安全风险控制系统。同时结合地铁工程设计及施工情况,综合运用BIM+移动端、自动监测等技术,实现基于BIM技术的城市轨道交通安全智慧监测技术。

This paper combines BIM Technology with FEA analysis technology,takes the construction process of urban rail transit station near the existing railway as an implementation case,carries out the finite element analysis of subway station foundation pit excavation,and introduces BIM integration platform to realize the data format transformation of BIM management platform and the embedding of safety risk assessment model of deep foundation pit construction near the existing railway,and finally establishes the safety risk assessment model dynamic visual construction safety risk control system.At the same time,combined with the subway engineering design and construction,BIM+mobile terminal and automatic monitoring technology are comprehensively used to realize the intelligent safety monitoring technology of Urban Rail Transit Based on BIM Technology.
