締固めた凝灰岩と火山灰性粘土の混合土の剪断特性の異方性について

The consolidated undrained triaxial compression tests were performed for the specimen cut from vertical (V), parallel (H) and diagonal (D) by compacted plane． From these experiments, thereis no variance in stress-strain relations, pore pressure coefficient, compressive strength and strength parameters c^'and φ^'or c_<cu> and φ_<cu> among V, H and D specimen. From these results there is no anisotropy in the shearing properties of compacted soil mixed with tuff and volcanic clay. But, c^' and φ_<cu> are decreased considerably in the case of adsorption of specimen.
