The deformation and failure of strip footings on anisotropic cohesionless sloping grounds

Footing foundations are sometimes built on sloping grounds of natural sand which is highly anisotropic. The anisotropic mechanical behaviour can significantly influence the bearing capacity a foundation and failure mechanism its supporting slope. Neglecting anisotropy may lead to overestimated under-design foundations. A numerical investigation response slope under strip footing presented, placing special focus effect anisotropy. critical state model accounting for fabric evolution used. nonlocal method has been used regularize mesh-dependency solutions. Predictions footings slopes validated by centrifuge test data Toyoura sand. Compared data, an isotropic overpredict up 100% when parameters determined based horizontal bedding plane case. When where vertical, predictions be improved some cases but settlement at overestimated. soil body tends move along upon loading due non-coaxial strain increment caused slip surface appears deeper with lower preferred movement direction towards
