摘 要:在功能综合、管线复杂的机场基础设施工程设计过程中,管廊或地道等构筑物会穿越机坪或飞机滑行道。飞机轮压通过覆土扩散、叠加后会作用于构筑物顶板。构筑物上的荷载与飞机重量、飞机轮压布置形式及覆土厚度有关。结合某机场项目中的设计条件,参照相关国家及行业标准,探讨飞机轮压均布等代值法和等效均布活载法的2种飞机等效荷载计算方法,进行计算、比较和分析,将设计成果应用于工程,并为其他工程穿越机坪提供参考依据。In the process of airport infrastructure engineering design with comprehensive functions&complex pipelines,pipe gallery or underpass and other structures will cross the apron or aircraft taxiway.The aircraft wheel pressure will act on the roof of the structure after it diffuses&superposes through the covering soil.The load on the structure is related to the weight of aircraft,the arrangement of aircraft wheel pressure and the thickness of overburden.Combining with the design conditions of an airport project and referring to the relevant national&industrial standards,it discusses 2 kinds of aircraft equivalent load calculation methods,namely equal value method of wheel pressure distribution&equivalent uniform distribution live load method,and carries out calculation,comparison&analysis.The design results are applied to the project and provide reference for other projects crossing the airport apron.
