[0002] Currently, when rail transit industry designers are designing reinforcement for rail transit shield tunnel connecting channels, they first need to manually draw the reinforcement range and longitudinal section mileage markings for the longitudinal section connecting channels in the rail transit shield tunnel longitudinal section design plan file based on the geological longitudinal section conditions. After the reinforcement design for the longitudinal section connecting channels of the shield tunnel is completed, the reinforcement mileage ranges for each section of the longitudinal section connecting channels are manually measured. Then, in the plane design plan file for the rail transit shield tunnel, the plane connecting channel reinforcement ranges and plane mileage markings are manually drawn one by one according to the reinforcement mileage ranges for each section of the longitudinal section connecting channels.
