[0002] Currently, when designing in-tunnel reinforcement for rail transit shield tunnels, rail transit designers must first manually draw the longitudinal section reinforcement scope and longitudinal section mileage markings in the rail transit shield tunnel longitudinal section design plan document based on the geological longitudinal section conditions.
