三维激光测量技术在机场道面病害区沉降测量的应用

Application of 3D Laser Scanning Measurement in Settlement Measurement of Airport Pavement Disease Zone

在民用运输机场的运营管理过程中,当道面稳定性不良时,可能会导致道面沉降问题,严重影响飞机起降的安全性,因此需要定期对道面进行检查。本文利用三维激光测量技术,对临沧博尚机场飞行区道面板块进行数据采集,分别进行了水准观测与三维激光扫描测量,对比二者测量精度、与测量效率的差异。试验结果表明,三维激光测量方法能够在满足机场道面建设规范前提下,缩短外业测绘人员劳动强度,并且三维激光测量技术在精度方面符合要求。

During the operation management stage of civil transport airports,poor pavement stability will lead to pavement settlement problems,which seriously affects the safety of aircraft taking off and landing,so that the pavement needs to be detected regularly.In this paper,the 3D laser scanning measurement technology is used to collect the datas of the pavement plate in the airfield area of Lincang Boshang Airport.Leveling observation and 3D laser scanning measurement technology are carried out to compare the measurement accuracy and efficiency.The test results show that the 3D laser scanning measurement technology can reduce the labor intensity of surveyors and meet requirements of accuracy,on the premise of airport pavement construction specifications.
