摘要
机场跑道长期使用过程中,道面板在地基沉降及外部环境作用下易发生开裂、脱空等病害,并在飞机动载、温度荷载等反复作用下,进一步发生板边或板角断裂,给飞机起降安全带来极大隐患。文章介绍了图像识别、传感器、H/FWD、探地雷达以及GIS无损检测技术,并针对这些技术优缺点及适用性进行深入分析。同时文章提出了针对断板检测的“内-外”结合的监测方法。
In the long-term use of the airport runway,under the settlement of foundation and the action of external environment,the crack and void is easy to occur in concrete pavement slab.Further,the edge and corner of the slab would fracture under the repeated action of the aircraft moving load and temperature load,which brings great hidden dangers to the takeoff and landing safety of the aircraft.This paper introduces image recognition、sensor,H/FWD,GPR and GIS NDT technology,which deeply analyze their advantages and applicability.Also This paper proposes an"inside-outside"monitoring method for the fracture of concrete pavement slab.
