In order to investigate the deformation and strength anisotropy of compacted decomposed granite soils, a series of unsaturated and saturated-drained triaxial compression tests were performed. The sample had three different angles of the axial direction to horizontal plane δ=0, 45 and 90 degrees. The compression strain of specimens subjected to an isotropic compression was influenced strongly by δ. And the effect of the δ on the strength was clearer in the unsaturated specimen than in the saturated specimen. Moreover, we propose a new procedure, which can be applied in the shear strength τ of the unsaturated specimen in consideration of the δ.
