某国际机场道面雨后冒水问题原因分析及处理措施

Cause Analysis and Treatment Measures of Water Pollution afterRain in an International Airport

某国际机场跑道沥青道面出现雨后冒水现象,国内外经验丰富的相关专家对现场进行了勘察,根据以往的经验,对机场道面雨后冒水情况做了详细的观察和数据理论分析。调查发现,项目所在地原地质情况较差,基本受力层材料由珊瑚砂颗粒组成,项目所在地地下水位高,而跑道设计横坡度偏小,造成道面宽排水不畅。因此,采用孔隙大的道面结构层SMA-13面层,雨水易渗入与地下水贯通,雨后地下水位拔高而造成冒水。经过现场观测和试验检测,最终得出结论,机场道面施工质量合格。

After the rain water appeared on the asphalt pavement of an international airport runway, experienced ex perts at home and abroad conducted a survey on the site, based on past experience, detailed observations and theoreti cal analysis of data on the water flooding of the airport pavement after rain were made. The investigation found that the original geological conditions of the project site were poor, the material of the basic stress layer was composed of coral sand particles, the groundwater level of the project site was high, and the runway design had a relatively small slope, resulting in poor drainage of the wide pavement. Therefore, the pore surface structure layer SMA-13 was adopt ed, rainwater easily penetrated and penetrated the groundwater, and the groundwater level rose after the rain, causing water to leak. After on-site observation and testing, it was finally concluded that the quality of the airport pavement was qualified.
