中美机场跑道平整度评价指标对比分析

Comparative Analysis of Evaluation Indexes of Runway Flatness Between China and America

为更好地服务于青岛新机场跑道施工效果检验和服务水平评价,对跑道平整度指标进行研究。针对我国民用机场跑道平整度评价指标(IRI)和美国联邦航空局评价指标(BBI)之间的差异,在实测37条跑道纵断面不平整激励下,对两者的相关性和适应性进行计算分析。结果表明:IRI和BBI相关性较差,实际使用时不能换算;借助ProFAA软件仿真得到飞机滑跑动力学响应,研究表明BBI相比于IRI更能有效预测飞机动力学响应;我国跑道平整度评价指标主要参考公路平整度的做法不太合理。

In order to better serve the effectiveness of runway construction and the evaluation of service level of Qingdao new airport,the index of runway flatness is studied.In view of the difference between the runway evenness evaluation index(IRI)of Civil airports in China and the evaluation index of Federal Aviation Administration(BBI)in the United States,the correlation and adaptability of the two indexes were calculated and analyzed under the measured longitudinal section uneven stimulation of 37 runways.The results showed that the correlation between IRI and BBI was poor and could not be converted in practice.The dynamic response of aircraft taxiing was simulated by ProFAA software.The research shows that BBI is more effective than IRI in predicting the dynamic response of aircraft.It is not reasonable that the evaluation index of runway flatness mainly refers to highway flatness in China.
