Abstract 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 on Mikasa consolidation theory and Voigt-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.

Key words： foundation loess high-filled foundation post-construction settlement in-situ monitoring modified FDA method compression test
