Experimental study on compaction and strength shear characteristics of intermediate soil consisted of various fine content

As for the research to understand a physical concerning intermediate soil mechanical attribute, it has been executed since the past, and some valuable learning are obtained. However, there is innumerably the ground material that exists naturally, and all characteristics are not necessarily understood.
On the other hand, the constitution formulation to connect a stress - strain of the soil distinguishes sand and clay and expresses it, it was common to handle. Because, the phenomenon that becomes a problem by the true ground is different at sand and clay. The sand cause liquefaction, and the clay cause compaction subsidence behavior. However, a recent composition formulation becomes possible to distinguish neither sand nor clay to express the dynamics behavior of both by few parameters. Therefore, it comes to the stage where the behavior of intermediate soil that has the characteristic of both is adequately expressible.
In addition, there is a report that damage in the embankment made with intermediate soil is remarkable in the ground hazards of a recent earthquake and the flood damage. Therefore, it is thought that the research on intermediate soil will be advanced further more. On the basis of such a background, I want to grasp the influence on a physical characteristic, the compaction characteristic, and the shear characteristic that the difference of fine content brings by using intermediate soil that mixes sand with clay.
In the present study, unconfined compression test and triaxial compression test to various physical tests, the soil compaction test, and the soil compaction samples are done, and the correlativity and the mechanism of each result are considered.
