摘要： 结合西南某高填方机场监测资料，分析高填方地基沉降几种预测方法的优缺点,根据填方体和原地基各自沉降规律的不同特征，运用三轴实验所得ep曲线、对数模型、经验公式等方法对填方体沉降进行预测分析，用对数模型、分层总和法等方法计算原地基沉降,并与地表监测数据进行对比分析。

Abstract: Abstract\ [WTBZ]This paper presents a case history on settlement monitoring results on an airport constructed with high fills. Several settlement estimation methods of high fill ground are examined with the observed data. The paper analyzes the settlement characteristics of the fill materials as well the original foundation soils. Different settlement prediction models, such as ep curves, logelogp model, empirical relationship as well as the numerical models are established from the large diameter triaxial test results. The settlement of the high fills are predicted by several different methods, such as, loglog model, summation of sublayers as well as numerical analysis. The advantage and disadvantage of these settlement prediction methods are compared with the observed data.
