摘　　要：对国内某中南部运输机场跑道同位置测线脱空状态进行检测,并进行脱空判定分析,得出机场跑道左测线脱空发展80%,右测线脱空发展42.7%。针对这一测试结论开展脱空发展成因分析,就降水排水因素、跑道荷载作用因素以及跑道使用时间因素对跑道脱空增长的影响进行量化分析,横向对比国内发展情况及规模相近的若干机场,并建立相关模型,研究结果表明:降水量每增加200 mm,脱空率会相应上升8.16%左右;跑道使用时间每增加1年,脱空率会相应增加2.4%左右;跑道荷载作用在机场正常稳定发展的情况下,对于脱空发展并无明显的特征关系;排水作用与脱空发展也存在一定的量化关系。该研究成果为吞吐量为1 500万左右、年客货增长率为15%左右的机场道面板脱空状态分析及脱空率预测提供重要参考依据。In this article,the state of runaway at the same location on a runway in a central and southern transportation airport in China was detected,and the runaway determination analysis was performed.Development 42.7%.Based on this test conclusion,the analysis of the cause of the development of runaway was carried out.The impacts of precipitation and drainage,the load factor of the runway,and the use time of the runway on the runway’s growth were quantified.Establishing a relevant model,the research results show that:for every 200 mm increase in precipitation,the emptying rate will increase by approximately 8.16%;for each additional year of runway use,the emptying rate will increase by approximately 2.4%;the role of runway loading at the airport is normal and stable Under the circumstances,there is no obvious characteristic relationship for the development of emptying;there is also a certain quantitative relationship between the drainage effect and the development of emptying.The research results provide an important reference for the analysis of the emptying state of the airport panel and the prediction of the emptying rate at a throughput of about 15 million and an annual passenger and cargo growth rate of about 15%.
