To investigate how different dry densities affect the mechanical properties of remolded loess under directional shear stress,a series of tests were carried out using a GDS hollow cylinder torsional shear apparatus on Qinghai remolded loess.The focus was on understanding how chan-ges in dry density affect the strength and deformation of remolded loess when the average princi-pal stress,intermediate principal stress coefficient,and principal stress direction angle remain constant.The results show that the failure strength of remolded loess increases as dry density in-creases under the directional shear stress.Furthermore,the initial dry density significantly affects the development patterns of octahedral shear strain and principal strain.The normalized strength of remolded loess shows an approximately linear increase with higher dry densities.During the later stages of shear failure,the principal stress direction and strain of remolded loess become in-consistent,showing an obvious non-coaxial phenomenon.Notably,at a dry density of 1.72 g/cm3,the non-coaxial angle at shear failure exceeds 12°.
