Abstract:  In order to realize the standardization and automatic mapping of the plane and longitudinal section of the metro shield tunnel, improve the drawing efficiency, and reduce the mistakes and collisions, the rapid drawing method of the plane and longitudinal section of the metro shield tunnel are researched. First, the public parameters in the plane and longitudinal section of the metro section is extracted and input them as a separate module. In the plan, the centerline of the metro line is located according to the centerline of the existing line, the center mileage, and the corresponding location of the terminal station. On this basis, automatic drawing, marking and modification is performed, and multiple standard drawings according to section line shapes are automatically produced. In the vertical section view, this method performs horizontal and vertical zooming in different scales, positioning in intervals, and then automatically drawing, marking, and modifying, positioning the different plot areas, and creating a standard vertical section block diagram with adaptive length in the horizontal direction. And a standard vertical section block diagram with adaptive length in the horizontal direction is created. By testing the research results, it can be known that the software can greatly improve the work efficiency of designers.
