为了进一步探索黄土高填方机场工后沉降的形成机制，以便于对其进行预测，以吕梁机场试验段为研究对象，结合大量的原位监测资料和室内压缩试验，采用修正FDA方法，试图将工后期排水固结变形和次固结(蠕变)变形进行分离，并采用基于Mikasa固结理论和Voigt-Kelvin黏弹性模型的沉降量–沉降速率曲线法进一步对该方法进行对比验证。研究表明：黄土高填方地基工后总沉降中约74%的沉降分量为深厚黄土地基的主固结沉降，其余的沉降主要以原地基及填筑体的蠕变引起，故基于修正 FDA 方法在分析黄土高填方工后沉降量形成机制的应用中比较符合工程实际，对类似工程的设计和工后沉降预测有一定的指导意义。

Based on the in-situ monitoring data and compression tests,the modified filed deformation analysis(FDA) was introduced to deeply discuss the formation mechanism of the post-construction settlement components and predict the long-term settlement of the high-filled embankment on the background of Luliang airport over deep loess foundation. The results were verified by the settlement values and settlement rate curves based onMikasa consolidation theory andVoigt-Kelvin viscoelastic model. The results show that the primary consolidation settlement of foundation is about 74% of the total post-construction settlement,and the rest of that is the creep settlement of the foundation and the high-fill body. This approach mentioned above is roughly consistent with the actual engineering,and could offer some valuable guidance to the design of loess-high filled and the post-construction settlement prediction analysis of engineering.
