A 1'x1' square concrete pile is embedded 20 feet in clay with an undrained shear strength of 2,800 psf. Based on the LaTeX: / alphaα-method and LaTeX: / alphaα-values of Terzaghi et al. (1996), what is the ultimate shaft friction, Qs in pounds? Use pa=2,000 psf.

    Check the explanation

    Explanation:

    The IC-96 technique offers the central assumption that the ultimate shaft friction is for the most part governed by the interface friction angle of the reconstituted clay as can be stipulated by the ring shear tests as well as the horizontal (radial) effective and efficient stress acting against the pile surface at failure.

    we can solve the question above by:

    Qs = PL x ∞

    = 0.75 x 2000 x 2 (1+1) 0.75

    = 4500DCF
