Granular Soil Long-Term Cyclic Loading

5 Granular Soil Long-Term Cyclic Loading 

Long-term cyclic loading leads to a progressive failure whereby a few soil grains move around the fluke during each cycle of load. High safety factors of 8-10 are recommended for this loading condition. 

Holding capacity factor N, versus relative depth for cohesionless soil c = 0. (From Taylor, R.J. et al. Handbook for Uplift Resisting Anchors, US Navy Civil Engineering Laboratory, Port Hueneme, CA, 1975. With permission.)
