人工配合した中間土の強度発現機構に関する実験的研究

In order to make clear the strength development mechanism of intermediate soils, the direct shear tests were performed on artificially mixed soils to examine the influences of soil texture and consolidation pressure. The following conclusions were obtained:
(1) The shear strength characteristic of soils changes from that of sand to clay with increasing clay content and from that of clay to sand with increasing consolidation pressure.
(2) From the direct shear tests, the experimental constant _cσ_c characterizing the boundary between sand and clay was found to exist and vary with the clay content and consolidation pressure.
(3) The expreimental constant _cσ_cn characterizing the soil properties was also found.
