High Fill Embankment Settlement Of Soft Ground

The paper relies on treatment with soft clay foundation from a high-way in DaYu Sichuan province. It had practicality measure studied the roadbed transect with project representation meaning., which roadbed roadhead fill settlement movement and filling pressure movement, and through analysis to roadhead settlement rule, and acquired some worthful conclusion. Through specially experimentative study in room to foundation's clay, the paper has particularly studied the saturation soft clay's settlement coefficient of permeability's changemeent theory with the time. Combining with secant modulus, the paper set up the saturation soft clay's consolidation settlement model, which can reflect the stress time and settlment at the same time, and also simulative study to it.In term of soil theory, combined with sand drain consolidation theory, the paper set up composite foundation's consolidation settlement model based on gravel pile disposal, and compare the theory result with the actual measure result, the paper think that the gravel pile disposal composite foundation's consolidation settlement model can achieve the project basal request and have possibility ulteriorly perfect, which based on secant modulus theory.
