A Shelby tube sample was taken from a depth of 25 ft. The sample was extruded in a laboratory, thus subjected to zero total stress. Assume Ko = 0.5 and Ā = -0.1, determine the effective stress on the sample after extrusion. Use the basic Skempton (1954) and Ladd and Lambe (1963) approach to determine the change in pore pressure.arrow_forward

- The simplest and oldest nonrigid method is the Winkler method, which uses inde-pendent springs, all of which have the same ks. This method is an improvement over rigid analyses, but still does not accurately model soil-structure interaction,primarily because it does not consider coupling effects.arrow_forwardA very long steel drill pipe got stuck in hard clay at an unknown depth.
