WebCohesive Soils: The side friction versus pile movement (t–z) curve (fig. 16.78) for cohesive soils is given in the API RP 2A (2000) and is the same for compressive and tensile loading for driven pipe piles. As suggested by API RP 2A, without more definitive criteria, the maximum side friction, t max, at the pile-soil interface is taken as the ultimate skin friction, f. WebAbout: Cohesion (geology) About: Cohesion (geology) Cohesion is the component of shear strength of a rock or soil that is independent of interparticle friction. In soils, true cohesion is caused by following: 1. * Electrostatic forces in stiff overconsolidated clays (which may be lost through weathering) 2. * Cementing by Fe2O3, Ca CO3, Na Cl, etc.
