摘　　要：为研究跑道主要功能指标对飞机和跑道的影响,首先,通过三维激光扫描技术构建三维道面高程模型,较为准确地反映道面平整度和纵横坡坡度信息,当跑道全长范围内的国际平整度指数(international roughness index,简称IRI)等于0.855 m/km和分段IRI均小于规范规定值1 m/km时,该机场跑道平整度处于“优”;其次,结合道面高程数据计算得到的着陆过程3个阶段平整度影响系数最大值(1,1.185,1.145)可知,平整度对飞机着陆过程影响大小排序依次为减速阶段、滑行阶段、接地阶段,与机场管理机构日常记录得到的结果一致;最后,通过间隔6年的2次点云数据对比表明,飞机重复起降荷载对道基土压实有利于其抵抗自然疲劳,也说明为节约造价而对跑道中部采用的减薄设计是合理的。To study the impact of runway functional indicators on aircraft and runway performance,a 3D runway elevation model is constructed using 3D laser scanning technology to reflect the roughness of the runway and the longitudinal and horizontal slope information more accurately.When the international roughness index(IRI) within the full runway length is 0.855 m/km and the segment IRI is less than 1 m/km,the runway roughness is recognized as "excellent".Secondly,according to the maximum influence coefficients of roughness in three stages(1,1.185,1.145) calculated by combining the elevation data,it can be seen that the influence order of roughness on aircraft landing process is deceleration,taxiing and grounding stage,which is consistent with the results obtained by the daily records of the airport manager.Finally,the comparison of two point cloud data with an interval of 6 years shows that the compaction of the foundation by repeated taking-off and landing load is beneficial to its resistance to natural fatigue,indicating that the thinning design of the middle runway is reasonable to save cost.
