During the tunneling process of the shield machine, the locator data is transmitted in real time to the shield machine model in the monitoring system platform. The shield machine model is driven by the locator data and moves forward in real time with the locator data. In conjunction with the surrounding geological profiles and mileage data, the shield machine excavation position and the number of completed tunnel construction can be obtained in real time.

8. The method for simulating double-hole tunnel shield excavation construction based on BIM and digital twin according to claim 1, characterized in that: The method for realizing the three-dimensional visualization display of the tunnel segment installation progress in step S4 includes: A corresponding QR code label is pasted on each segment to implement QR code management during the production, transportation and installation processes. When the segment is installed, the segment identification position is identified by scanning the QR code, and the segment identification position information is automatically transmitted to the monitoring system platform. The monitoring system platform automatically displays the status of the segment identification position that has been installed and displays the QR code number of the segment.

9. A computer-readable storage medium having a computer program stored thereon, characterized in that: When the program is executed by the processor, the steps of the double-hole tunnel shield excavation construction simulation method based on BIM and digital twins as described in any one of claims 1 to 8 are implemented.

10. A computer device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that: When the processor executes the program, it implements the steps of the double-hole tunnel shield excavation construction simulation method based on BIM and digital twin as described in any one of claims 1 to 8.
