Abstract：
To achieve the comparison of shield tunnelling monitoring information and simulation data and safety warning under complex geological conditions, this study takes practical engineering projects as the research object.By digitizing the information of shield tunnelling objects and using BIM (Building Information Modeling) technology to establish a three-dimensional geological model, a set of shield tunnelling safety simulation and visualization monitoring early warning system is proposed based on the combination of BIM 4D model and finite element simulation model. Through color-coded warning and model visibility, the linkage between numerical model and geological model is realized, achieving the automation and precision of simulation warning. Practice has shown that this system can effectively solve the problem of simulation and optimization comparison of construction schemes, and has a good effect on rapid data processing and prediction of adverse trends.
