摘要
圭亚那政府为促进国内旅游业的可持续发展,拟对现有国际机场跑道进行扩建,以满足宽体飞机的飞行要求。扩建区域以粉细砂垒筑成高台,然后铺设路基及沥青面层。针对跑道硬化区域雨水径流量和峰值径流量增加的现象,结合高回填砂层排水性能强的特点,合理设计跑道扩建段的排水系统。排水系统设计结合机场的地理位置,当地气象以及跑道坡度导向等因素综合考虑,通过构建集水挡坎、集水坑等排水构筑物以及布设排水管等措施,对跑道区降雨径流进行有效管控,实现流畅的排水过程,维持跑道所在高回填平台的稳定,保证跑道安全。
In order to promote the sustainable development of the domestic tourism industry,the Guyana government plans to expand the existing international airport runway to meet the flight requirements of wide-body aircraft.The expansion area is built in the form of high platform with fine sand,and then the subgrade and asphalt are laid.In view of the fact that the increase of rainwater runoff and peak runoff in the hardened area of the runway,the drainage system of the extended runway is designed reasonably in combination with the characteristics of strong drainage performance of the high backfill sand layer.The drainage system,in combination with the geographical location of the airport,local weather and runway slope guidance and other factors,can effectively control the rainfall and runoff in the runway area through the construction of drainage structures such as water retaining bank and sump,as well as the layout of drainage pipe and other measures,so as to achieve a smooth drainage process,ensure the stability of the high backfill platform where the runway is located,and ensure the safety of the runway.
