WebShallow footings solve the uplift issue by harnessing the self weight of the building as well as using an adequate plan area for the footing itself to provide stabilisation. However if the uplift is sufficiently large, the friction capacity of some pile foundation types can quickly solve this dilemma in a more efficient manner. WebNov 6, 2024 · This sliding force is resisted by the friction between the underlying soil and the footing, and by the passive pressure at the front of the wall. When more sliding resistance is required, a shear key may be provided. The factor of safety against sliding equals the resisting force divided by the driving force, and the minimum value should be 1.50. cystectomy in dogs
