Effect Analysis of Sandy Foundation Treatments in MU US Desert

In the research, some field tests on different groud treatments of sand, including water-treatment (hydrostatic deposition process and Water saturated layered rolling process), vibroflotation and dynamic consolidation were carried out to aeolian sands Subgrade in southern fringe of Mu Us desert. According to these test data, this paper had analyzed the changes on physical characteristics and carried capacity of aeolian sand foundation under different ground treatments. Then it summarized the advantages and disadvantages of different ground treatments for aeolian sand foundation, and discussed the function mechanisms of different treatment methods.
