摘　　要：以禄口国际机场二期工程项目为例,在分析飞行区场地地基土的工程特性和场地内不同地貌单元软土分布特性的基础上,结合机场上部荷载要求,提出了软土地基处理的方案。对沟塘区采用清淤换填法,漫滩区采用超载预压加排水板,漫滩区永久边坡(不含灯光带)采用水泥土搅拌桩与塑料排水板相结合的方法处理。通过施工期间的监测结果对软基处理效果进行了验证,表明本项目地基处理方法是可行的,满足设计要求。For Lukou International Airport Project Phase II, soft foundation treatment schemes are proposed according to the foundation work characteristics of the airfield venue and the different landforms distribution characteristics of soft soil in airfield venue, and the upper load requirement of the airport, including a dredging and replacement method for sand pond area, a surcharge preloading and drainage plate scheme for floodplain area, cement mixing method and plastic drainage plate for the perpetual slop of the floodplain area （excluding lamplight belt）. The soft foundation treatment effect is verified by the monitoring results obtained during construction, and the results show the treatment methods of this project are feasible and meet design requirements.
