Other AbstractThe biaxial compression apparatus is employed to conduct tests on prism-shaped granular materials with stress path of axial loading-unloading and reloading.The whole process of fracturing and forming the breakage bands of the granular materials subjected to axial loading-unloading are observed under different lateral pressures.When the lateral pressure is relative low,the deformation of the sample composed of granular materials mainly comes from the slip and crush of the granular materials;and with the increase of axial strain the volume of the sample first contracts then expands;the lateral deformation slightly contracts at the initial stage of loading and then extrudes all the time.When the lateral pressure is relative high,the deformation of the sample mainly comes from the compression between granular materials,and granular materials compression and crush;and with the increase of axial strain the volume of the sample always contracts,contracting much with higher lateral pressure;the lateral deformation contracts all the time.During the stress cycle of axial loading-unloading,the reversible deformation is bigger with lower lateral pressure and smaller with higher lateral pressure.
