首先使用FLC3D有限差分软件研究土层弹性模量、重度、填土高度对跑道道面中心点沉降的影响。数值计算结果表明：土层弹性模量增加，沉降变形减小，但不明显；填土重度和填土高度增加，沉降变形都增加较大。然后以某机场工程为背景选取跑道典型断面计算其在不采取任何地基处理情况下的工后沉降。填方工后沉降由原地基沉降和填筑体沉降两部分组成。原地基变形根据太沙基一维固结理论计算，上部填方沉降由工程经验公式得出。参考沉降计算结果，为工程后期采取合适的地基处理方案提出建议。

Firstly,the influence of modulus of elasticity of soil layer,unit weight and the height of fill to the settlement of the center Point of the runway surface is researched by using the finite difference software of FLC3D . According to the result:with the modulus of elasticity of soil layer increased,the settlement and deformation were decreased,but not obvious;with the unit weight and the height of fill increased,the set﹣tlement and deformation were increased obviously. The tyPical cross﹣section is selected to calculate the set﹣tlement of the high fill embankment which is without ground treatment on the background of a certain air﹣Port Project. The Post-construction settlement of high fill consist of settlement of the original foundation and settlement of high fill. The settlement of the original foundation is calculated accurately based on one﹣dimensional Terzaghi consolidation theory and the settlement of uPPer fill is calculated by engineering em﹣Pirical formula. The latter Part of aPProPriate ground treatment Program selection can be ProPosed refer to the results.
