摘要
自2000年以来,国家在西南片区规划了大量的机场建设项目,且主要分布在四川盆地的红层地区,由于红层地区独特的地貌条件和岩土体物理力学性质,造就了其特殊的工程地质问题。本文通过分析四川盆地红层区的工程地质条件特点,结合红层机场实例,总结了四川盆地区红层机场建设中遇到的地基均匀性、地基稳定性及填料稳定性等工程地质问题,并分析了其发育规律,提出了相关建议,成果可为该地区机场建设提供重要参考。
Since the year of 2000,the country has planned lots of airport construction in the southwest area,mainly in the red beds of Sichuan Basin. The unique landscape and physical and mechanical properties of rock and soil in the red beds make the special engineering geological problems. Through analyzing the characteristics of engineering geological conditions of the red beds in Sichuan Basin,and combing with airport instance in the red beds,some engineering geological problems in the airport construction in red beds of Sichuan Basin are summarized,such as the foundation uniformity,foundation stability and filler stability. The development laws are analyzed and the relevant suggestions are put forward. The results can provide important reference for the construction of airport in the region.
