System and method for optimally designing thickening layers of airport pavements

Abstract

The invention discloses a system and a method for optimally designing thickening layers of airport pavements. The system for optimally designing the thickening layers of the airport pavements comprises an automatic optimizing unit, an automatic computing unit, an interactive unit and an automatic drawing unit. The method for optimally designing the thickening layers of the airport pavements includes steps of using spatial curved surfaces as the surfaces of the pavements with the thickening layers and designing geometrical models; building mathematical models for optimally designing the thickening layers of the pavements by means of using design grade and elevation of control points as design variables; creating constraint conditions which conform to relevant specifications of current military aviation and civil aviation; providing the optimal process for optimally designing the thickening layers of the pavements. The system and the method have the advantages that the system and the method are applied to designing more than ten rebuilt or expanded airports such as the Baita airport in Hohhot, the concrete thickening layer engineering quantity can be saved by about 5%, all design drawing can be implemented, an acquired design scheme completely conforms to technical standards, and the design period can be shortened and is about 10 days.

Description

technical field [0001] The invention belongs to the field of airport construction, and in particular relates to an optimized design system and method for an airport pavement thickening layer. Background technique [0002] After long-term use, the quality of airport pavement will be reduced under the action of load and natural conditions. In order to restore the good quality of pavement, airport pavement renovation is generally carried out by building overlays. At the same time, because the old airport is designed according to the original design of the aircraft, when the aircraft in use changes, it is possible to propose a new design for the airport. Therefore, the existing airport needs to be reconstructed. No matter what type of overlay is used, it involves the terrain design of the overlay layer. The overlay layer design scheme is generally determined comprehensively by considering factors such as the condition of the old pavement, load, and service period. However, due ...
