Dynamic Drainage Preloading Soft Soil Study

The dynamic drain consolidation method is a kind of economical, safe and speediness new foundation method, in which the drain system are set firstly, then the preload are added, and then the heavy tamping are constructed.But the dynamic drain consolidation does not have the convinced theory and the computation formulations, the insufficiency of the dynamic drain consolidation constrain it's development, thus this study issue is put into the study agenda to solve the problem. The soil mechanics is very complex for the soils' factors are dispersed . The foundation treatment technique relating to the soil mechanics is also perplexing, regional, experiential and unclear.After several month's study, some achievements on the dynamic drain consolidation method are obtained : the systematic and scientific conception of the dynamic drain consolidation method is expressed; the mechanism of the dynamic drain consolidation method is explained on the different views; the way to modify the dynamic consolidation model is brought forward which pave the way for the further study; the systematic theories of the dynamic drain consolidation method are developed and the relative computing methods are also formulated; the geotechnique testing methods for the dynamic drain consolidation method are also provided; the principal documents for the dynamic drain consolidation method design, construction and testing techniques are developed in this dissertation .The succeed of this study issue is helpful to expand the foundation treatment domain, is also helpful to popularize the dynamic drain consolidation method. It has the great practical usage for the NanSha new economy and technology development region of Guangzhou.
