摘要:

在大量调研国内外机场沥青道面结构设计方法的基础上,以昆明新机场为依托,采用美国6E法、美国6D法、中国民航沥青道面结构设计方法及课题组研究的设计新方法对昆明新机场沥青道面结构的厚度进行了论证分析。结果显示,中国民航法设计的道面结构总厚度较美国6E法设计厚度厚27cm,课题组研究的设计新方法与美国6E法较为接近,且基于道面结构动态力学响应得到的道面结构总厚度要比静态的厚15cm。通过对昆明机场道面结构厚度的论证,探讨了现有设计方法中存在的问题,提出了一些规范修订的改进建议,为中国民用机场沥青混凝土道面设计理论的完善和修订提供一些理论参考。

Abstract:

Based on a large survey of currently representative design methods of asphalt concrete airport pavement in the world,structure thickness of Kunming New Airport is analyzed using the design methods of 6E,6D from FAA,China's civil aviation asphalt pavement design method and the new design method from the author's research group. The results show that the total thickness of pavement structure designd by the Civil Aviation Specifications of China is thicker than the 6E of FAA by 27 cm;the total thickness of the new design method from author's research group is closer to the 6E of FAA;the total thickness based on the the pavement structure dynamic mechanical response is thicker than static mechanical response by 15 cm. After discussing the thickness of Kunming New Airport pavement,some problems of the present design method are discussed in details. Besides,the development of design method in China is discussed and some advices are put forward for further design. Through the research,some technical references are provided for the improvement of our design theory of asphalt concrete pavement.
