Shield Construction Control Based on Integrity of Pavement Structure of Airport Runway

Abstract:

In order to ensure the integrity of pavement structure, and to maintain the pavement structure and foundation to be in contact and in co deformation, the formula of the accepted maximum settlement δmax is derived according to the law of foundation settlement while the shield goes through the flight zone, therefore, the safety standards for airport pavement structure are proposed. As a result, the shield construction parameters can be controlled effectively to ensure the safety of the construction.
