An research on the stability of the high embankment foundation of an airport in Guizhou;

Firstly,authors presented the main influencing factors of post-construction settlement of transformation substation high fill foundation in two ways of experiment and theory, which is fill height and deformation modulus,and a primary formula of post-construction settlement of foundation was given.

By using FLAC~3D program to simulate real construction process,the settlement of the high fill foundation especially differential settlement,which has the most powerful influence on Jiuzai-Huanglong airport is quantitatively analyzed and evaluated.

Prediction of the post-load settlement of high embankment by artificial neural network;

Prediction of the post-construction settlement of the high embankment of Jiuzhai-Huanglong airport;

Finite element analysis of displacement and stress distribution of high embankment;

On the basis of the long field investigation of the Jiuzhai\|Huanglong airport project and the data collected from the initial survey and detailed survey and the high filled ground treatment detection,the weak soils which are put forward in the groundworks is profoundly and systematically studied.

Taking an airport s high embankment in the karst region of Guizhou as an example,the compressional creep test of sandy gravel as the filling material is studied.

By taking the embankment, with a height of 104 m, of Jiuzhai-Huanglong airport as an example, similar conditions of compressional creep tests simulating the high embankment using filling material of sandy gravel were investigated.
