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;

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.

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.

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

Filling technology of blowing sand for high embankment in lake area;

Based on the application and practice using impact roller to a high embankment of highway,which is filled by soil-rock foundation packing material with high content of stone(60%–70%),an impact compaction technology for high embankment is developed.

This paper illuminates the high embankment of fast construction as the bridge prefabrication site from three aspects of processing natural subgrade,filling embankment and strengthen measures,and make it prepare for the construction,piling up,transport and assembly of prefabricated components.
