[0002] Currently, when designing ground reinforcement for rail transit shield tunnels, rail transit designers must first manually draw the longitudinal section ground reinforcement range and longitudinal section mileage markings in the rail transit shield tunnel longitudinal section design plan document based on the geological longitudinal section conditions. After the shield tunnel longitudinal section ground reinforcement design is completed, the ground reinforcement mileage ranges for each longitudinal section are manually measured. Then, in the rail transit shield tunnel plan design plan document, the planar ground reinforcement ranges and planar mileage markings are manually drawn, corresponding to the ground reinforcement mileage ranges for each longitudinal section.
