If field test methods are adopted such as designing based on SPT N values, higher FS values are chosen.

Webb2 o For Piles in Clay; Equation (1) will be: Since for piles in normally consolidated clay the undrained condition is control, φu =0 and δ=0 ∴ ks.σv′.tanδ=0 and c =cu =qu / 2.Also, for φu =0: Nc =9(from Skempton chart for circular or square), Nq =1.0 and Nγ =0.0. In addition to, the difference between [Ab.q−W p] is only in (γconc.−γsoil)which is very small, that … WebbThe methods for design of pile groups that are pre sented are empirical in nature and include design against bearing ca pacity failure and design against excessive pile and soil settlement. Because this is a state-of-the-art presentation, no definite conclusions are given concerning the use of one design method in preference to another.
