Abstract: In order to study the influence of stress and humidification conditions on the cumulative deformation characteristics of compacted granite residual soil under train load, cyclic hollow torsional shear and cyclic directional loading tests were carried out on compacted granite residual soil with confining pressure, dynamic stress amplitude and water content as variables. Results show that the rotation effect of principal stress axis under cyclic torsional shear stress path increases the cumulative... More
