Abstract

Abstract

On the basis of the construction on a high-filled collapsible loess foundation of a airport in the northwest of Shanxi，according to the initial design and the initial stability analysis results of the slope，the numerical stability analysis of 10 typical cross sections of the high-filled slope of the airport was performed by combined with a large-scale centrifugal model test． The research results showed that the slope of the airport was stable at natural moisture content， while unstable at full saturation． Deformations on the surface of the filling body were mainly vertical ones with horizontal displacements towards the outside of the slope． Also，the vertical deformation was bigger when it closer to the surface of the slope． The maximum shear strain of the slope was mainly concentrated on the contact surface between the filling body and the natural subsoil． Moreover，when the slope was broken，the displacements of the top and the bottom of the slope generally increased with the increase of the height and the thickness of the slope．
