摘要
对西南某机场跑道部分区域沉陷变形的情况进行专项调查,找到沉陷区域并评价其严重程度,帮助机场运营管理单位掌握飞行区道面状况.首先将跑道检测区按照沉陷程度分为十个闭合水准线路,分区测量点位高程;再将高程数据与设计数据对比分析,运用Surfer、Matlab软件制图呈现和计算跑道沉陷程度;结合道面纵、横坡坡度的改变判断跑道的适用性.评价结论为跑道沉陷部分体积约2 700 m3,约20％测量区域的横坡坡度不符合要求,为避免沉陷情况加剧,应在道面维护工作上做出相应应对措施.
Abstract
Through a special investigation on the subsidence and deformation of certain areas of the runway of an airport in Southwest China,this paper finds the subsidence area,evaluates its severi-ty and helps the airport operation and management unit to master the pavement conditions of the air-field area.Firstly,the detection area at the runway is divided into ten closed leveling lines according to the degree of subsidence,and the elevations of the points are measured in different zones.Then the elevation data with the design data is compared and analyzed,Surfer and Matlab softwares are used to present and calculate the subsidence degree of the runway.The suitability of the runway is judged by the change of the longitudinal and cross slope of the pavement.The assessment conclusion is that the volume of runway subsidence is about 2700m3.The gradient of approximately 20％of the measured area's cross slope does not meet the requirements.In order to avoid the aggravation of the subsidence,corresponding measures should be taken for pavement maintenance.
