利用无损探测技术研究机场道面错台成因

依托无损检测方法对某机场道面错台区域进行综合检测，得到引起该机场道面错台的原因：由于错台区域两侧道面修建历史不同，所采用的道面结构和材料不同，2种不同道面在飞机荷载和环境因素的长期作用下引起道面基层不均匀沉降，基层的不均匀沉降进一步反射到面层引起错台区域道面脱空，道面脱空和基层的不均匀沉陷最终引起道面错台．

Reason Analysis of Runway Pavement Faulting Using Nondestructive Detection Technology

Nondestructive detection technology shall be adopt to give a detailed inspection on the slab faulting areas, and a scientific and reasonable analysis on the inspection results will also be explained in this paper. In accordance with the comprehensive analysis of the inspection results, it shows that the main reasons for the faulting are. the different pavement construction history in each slab faulting side; varied structure and materials caused the uneven settlement of foundation in the long-term aircraft load and environmental factors, which further reflection to the pavement caused the void beneath the pavement. So it can be concluded that void beneath the pavement and the uneven foundation settlement are the final reasons for the pavement faulting.
