摘 要：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面層，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。

Abstract： After the rain water appeared on the asphalt pavement of an international airport runway， experienced experts at home and abroad conducted a survey on the site， based on past experience， detailed observations and theoretical 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 adopted， 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.

沥青路面常见的病害有积水、渗水、裂缝等现象，但沥青路面出现冒水的现象在国内还未有先例。某海外国际机场的主跑道沥青面层施工完成后，雨后一段时间（天气放晴）出现冒水问题。为了弄清楚发生冒水现象的原因，该机场邀请国外有相关经验的专家对现场进行勘察，根据以往的经验[1-2]，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，最终得出结论，机场道面质量合格。

1 项目地质情况分析

从项目地质情况来看，该项目场地位于印度洋北马累岛环礁区，陆域面积狭窄，地势低平，水文地质条件总体属于印度洋海洋环境。砂岛地质条件覆盖层较薄，透水性好，储水条件极差。根据野外钻探成果的分析，该项目场地内16.0m深度范围内的地层为：表层为人工填土层，其下为珊瑚砂层，下伏为礁灰岩。……
