摘　　要：传统的安全预警手段存在信息传递不灵活、表达效果不直观等问题,且现阶段在盾构隧道中基于BIM技术的深化应用尚未得到广泛重视。为解决这些问题,引入BIM技术实现快速可靠的盾构隧道结构分析及安全预警可视化方法。首先借助插口程序及代码实现BIM和有限元(FEM)间的模型及数据转换,从而实现基于BIM建模的快速有限元分析,再利用BIM的可视化优势将计算得到的结构安全系数直观地表现出结构的安全状态,从而实现基于BIM及FEM的盾构隧道结构安全预警可视化技术。结果表明,提出的安全预警可视化表达方法对隧道工程具有良好的效果。The traditional tunnel safety early warning methods have some problems,such as the inflexible information transmission,the non-intuitive expression effect and more.Otherwise,the deepening application of BIM Technology in the field of shield tunnel has not been widely valued.To solve these problems,BIM Technology is introduced to realize fast and reliable tunnel structure analysis and safety early warning visualization method.First of all,the model and data transformation between BIM and Finite Element Model(FEM)are realized with the help of socket program and code so that the rapid finite element analysis based on BIM modeling is realized.And then the paper visually displays the structural safety status of calculating structural safety factor by using the visual advantages of BIM,and realizes the tunnel structure safety early warning visualization technology based on BIM and mechanical analysis.The results show that the proposed method of visual expression of safety warning has good effect on tunnel engineering.
