Application Of BIM Technology In Tunnel Monitoring And Measurement And Advanced Geological Prediction

With the popularity of BIM in the world,the application of BIM technology in monitoring measurement and advanced geological forecasting has become an important direction of BIM technology research in tunnel engineering.This article combines the tunnel BIM model and GIS technology to establish the Xiaofosi surrounding rock deformation monitoring system and carried out a specific application,then the research was carried out on the visual display of the geological body along the tunnel.The main contents and results of the thesis research are:1.Introduce the research background,significance and current situation at home and abroad of thesis writing,then explain the research content and method,and systematically elaborate the relevant theories of BIM technology and GIS technology as the theoretical basis of this article.2.Establishing the BIM tunnel model based on the fineness and information granularity of the highway tunnel,and integrate the BIM model with the GIS model.According to the fineness and information granularity of highway tunnels and the characteristics of design and construction,establish tunnel geological model,structural model and monitoring points rapidly,Through data conversion,the fusion of BIM model and GIS model is realized,and the fusion conversion process and main fusion development ideas and function points are introduced.3.Implement the early warning application and feedback construction of tunnel monitoring and measurement in the established platform.Relying on a tunnel project,the BIM + GIS monitoring platform has been established,the platform integrates its three-dimensional visualization and information data integration capabilities to achieve integrated processing,analysis and timely sharing of monitoring data,predicting the deformation boundary value of tunnel surrounding rock in the early warning and forecasting system of tunnel engineering monitoring and measurement,initially implement the early warning plan to guide the construction based on the monitoring data and data.4.Based on the Revit platform,the visualization of the advanced forecast visualization in the tunnel geology and the construction face is carried out.According to geological survey and construction data,realize the geological cataloging of the palm face and the geological reconstruction of special sections of bad geology,to achieve the effect of 3D visualization of the surrounding rock area around the tunnel;according to the geological model,realize the visualization of the regional section to achieve the surrounding rock prediction,key spatial query analysis and support display.Finally,this paper summarizes and prospects,summarizes the main content of the research,and prospects the application of BIM technology in tunnel engineering.The research content and results of this paper will improve the safety management level of tunnel construction,and have certain reference significance for promoting the application of BIM technology in tunnel engineering construction monitoring and the development of advanced geological prediction 3D visualization,and also will guide the operation and management of the tunnel in the future.
