摘要： 在我国东南部的机场建设中，场区往往会存在大面积的软土。软土具有高压缩性、低强度等特性，极易导致飞行区道面产生较大的不均匀沉降和边坡失稳，因此，机场飞行区的软土地基处理是机场建设过程中的关键。针对软土的工程特性，依据规范中对飞行区地基沉降、强度及边坡稳定性的要求，结合四个机场飞行区软土地基处理工程案例，着重从地基变形和强度方面展开分析，探讨了不同软土地基的处理效果，提出了飞行区软土地基处理建议。

Abstract: Soft soils are frequently encountered in the airport runway constructions in Southeast China. The high compressibility and low shear strength of these soft soils can often result in large areas of differential settlement and shear failure within the runways. Therefore, the soil improvement is the critical issue in the airport construction. This paper presents the code requirements of total and differential settlement, strength and stability aspects in the runway construction. The results of four different soil improvement projects and their correspondent soil improvement recommendations are also presented.
