摘　　要：基于成都新机场试验区实时监测资料对各地基处理区原地基软土、填筑体的沉降变化规律及孔隙水消散规律进行分析.在对比研究对数法、双曲线法、指数法的沉降预测结果后发现,双曲线法更符合成都新机场的沉降趋势,利用双曲线法对成都新机场试验区的监测点进行了工后30年的沉降预测,并基于研究成果发现成都新机场试验区地基处理效果符合设计要求.Based on the real-time monitoring data of the test area of Chengdu New Airport,this paper analyzed the settlement law of soft soil and filling body and the law of pore water dissipation in the base treatment area.After comparing the settlement prediction results of logarithm method,hyperbolic method and exponential method,it is found that the hyperbolic method is more in line with the settlement trend of Chengdu New Airport,and the monitoring point of Chengdu New Airport Experimental Area has been predicted for 30 years after the completion of the project using hyperbolic method.Based on the research results,it is found that the ground treatment effect of the test area of Chengdu New Airport meets the design requirements.
