| Research Abstract |
This paper is discussed about the application of the vacuum consolidation to the high moisture content soil/intermediate soil. The followings are obtained. 1) Using the SYS Cam clay model ,which is the elasto plastic constitutive equation, the shear behaviors of the high moisture content soil/intermediate soil are appropriately expressible and the mechanical behavior is clarified. 2) The vacuum pressure load tests were performed for the intermediate soil, and it was clarified that that soil improvement by vacuum pressure was effective for the intermediate soil. 3) The numerical simulations were performed, and the mechanism of soil improvement for vacuum pressure is clarified. In addition, the possibility of soil improvement with embankment together was examined.
