Influence of spheroidal and blade-shaped coarse particles on the shear evolution and spatial deformation of sliding zone soil

Key Points

• Shear evolution significantly varies with different particle shapes, especially between spheroidal and blade-shaped particles.
• Spatial deformation patterns are notably influenced by the arrangement of coarse particles within the soil matrix.
• Assessment using advanced soil testing techniques shows the distinct behaviors under shear stress in sliding zones.
• Implications suggest that understanding particle shape can enhance soil management strategies and engineering applications.
