摘　　要：该文以新建苏中江都机场为背景,针对沿海地区软弱地基,结合机场工程地基沉降和稳定性要求,采用超载预压方法对站坪地基进行处理,制定现场监测元件布设方案,并实时跟踪观测,分析了地表沉降、分层沉降、孔隙水压力、地下水位、侧向位移在超载预压情况下的变化规律,为相关工程的设计和研究提供参考。With the background of the newly built Jiangdu Airport in the middle of the Jiangsu Province,the subgrade of airport ground is treated by the surcharge preloading method and the arrangement scheme of field monitoring points is set down by aiming at the weak subgrade of coastal area and according to the subgrade settlement and stabilization requirements of airport engineering.The real time tracking observation is implemented.The article analyzes the variation law of ground surface settlement,layered settlement,pore water pressure,underground water level and lateral displacement under surcharge preloading,which can be referred for the design and study of the similar projects.
