Tunnel engineering safety risk monitoring system and method based on BIM

Abstract

The invention belongs to the technical field of building information model information, and particularly relates to a BIM-based tunnel engineering safety risk monitoring system and method. According to the system, a field monitoring module is arranged in a monitoring area of a tunnel construction field and is used for monitoring mechanical property data of a supporting system and stable state data of surrounding rock of a monitoring point in the current monitoring area; transmitting the data to a data server; determining a risk assessment result of a monitoring point in the monitoring area through the risk assessment model, and transmitting the risk assessment result to a database; creating a three-dimensional BIM monitoring model, converting the three-dimensional BIM monitoring model into an IFC monitoring model, carrying out IFC monitoring information expansion on the IFC monitoring model, obtaining an expanded IFC monitoring model, and loading the expanded IFC monitoring model by adopting a visual early warning platform; the IFC monitoring model serves as an interaction standard of BIM monitoring model data and is written into the IFC attribute set of the monitoring model, the use efficiency of monitoring information is improved, the amount of information carried by the model is expanded to meet the requirement of visual monitoring, and real-time dynamic safety early warning of tunnel engineering is achieved.

Description

Technical field [0001] The present invention is a construction information model information technology field, especially involving a BIM -based tunnel engineering safety risk monitoring system and method. Background technique [0002] With the rapid development of my country's economy, the comprehensive national strength has improved significantly, and the field of infrastructure has also ushered in a leap -up development. According to statistics, at the end of 2020, my country ’s highway tunnel was 21,316, 219.993 million Yanmi, an increase of 2,249, 30.327 million extension, and fixed asset investment was 258.83 billion yuan, an increase of 10.4 % over the previous year. The country with the most complicated construction structure. However, the construction characteristics of the tunnel engineering itself have also caused frequent safety accidents. Defects such as low information transmission efficiency during construction, insufficient construction experience in relevant pers...

Problems solved by technology

However, the new monitoring technology still has problems such as high labor cost, low degree of visualization, and native data processing.

Moreover, the current tunnel information monitoring technology also has the following problems: (1) The 3D model is not effectively combined with the monitoring and early warning, and the 3D model and the monitoring data are relatively independent; Imperfect; (3) Information transmission lags behind in the process of tunnel construction defect disposal management, and it is impossible to track, deal with, and close quality hidden dangers; (4) Monitoring data early warning technology is not yet mature

[0005] At present, the BIM-based tunnel engineering safety monitoring visualization and risk prediction methods at home and abroad are not deep enough. Most databases can only store and read and write monitoring information. At the same time, the expansion of monitoring information in IFC standards still needs to be improved, and it is impossible to scientifically and rationally analyze tunnel engineering. The project carries out dynamic risk assessment, and the application of BIM technology stays in the local application
