A terrain optimization design system and method for a multi-runway and multi-taxiway large-scale airport

Abstract

The invention discloses a system and method for optimization design of the terrain of a large multi-track and multi-taxi-track airport. The system for the optimization design of the terrain of the large multi-track and multi-taxi-track airport comprises an automatic optimizing unit, an automatic calculating unit, an automatic drawing unit and interactive units. The method for the optimization design of the terrain of the large multi-track and multi-taxi-track airport comprises the steps that a spatial continuous twisted surface is adopted to symbolize the terrain designing surface of the airport, nonlinear mathematical programming is adopted to summarize the design variables such as the gradient and technical indexes into one mathematical model, and the design gradient and the control point elevation of the airport are solved with the working constraint set method. The system and method for the optimization design of the terrain of the large multi-track and multi-taxi-track airport are applied to terrain design of almost hundreds of domestic and foreign airports, such as the New Luanda International Airport in the capital of Angola and the International Airport of Xianyang in Xi'an; compared with a traditional section method or a traditional lattice method, the method has the advantages that the designing earth volume of the airport can be saved by about 15% on the premise that any take-off and landing requirements of planes are not lowered, the design process can be shortened to about ten days from the original one month, and drawing quality can be improved remarkably.

Description

technical field [0001] The invention belongs to the field of airport construction, in particular to a terrain optimization design system and method for a multi-runway and multi-taxiway large-scale airport. Background technique [0002] Airport terrain design is an important part of the entire airport engineering design. In the airport track engineering design, the airport terrain design cycle is the longest and the design workload is the largest. The task of airport terrain design is to design a reasonable flight site On the terrain surface, under the premise of meeting the safety requirements of aircraft take-off, landing, and taxiing, the amount of earth and stone works during leveling operations in the flight field area shall be minimized. [0003] For a long time, the terrain design of my country's airports has mainly followed the design method used for road and railway line selection - the "section method" design. Since roads and railways have small horizontal dimension...
