Proposal of determination method of soil parameters for coral gravel soils -interaction between skeletal structure of coral gravels and silty soil matrix

Coral gravel soil is a composite soil consisted of silty matrix and finger-coral gravels. In this study, a series of triaxial shear tests for coral gravel soils with different proportion in volumetric percentage of coral gravels were conducted to examine the influence of skeletal structure of coral gravels on the shearing behavior. In addition, another series of triaxial shear tests were conducted for undisturbed coral gravel soil samples with various grain-size distributions to find a governing parameter for the shearing behavior associated with the skeletal structure.
