BEARING CAPACITY AND SETTLEMENT OF PILE FOUNDATIONS

The discussers point out further aspects of limit point bearing capacity of piles in sand as well as the overlayered stratum and critical depth. It is noted that if phi (angle of friction) is the parameter that can describe the part in p sub o N sub q, it cannot alone explain the part in q sub 1, which essentially depends upon the compressibility phenomena. Experiments on various sands have shown that the relationship between q sub 1 and phi is valid only for sands, the physical and mechanical properties of which are not very different. For homogeneous medium, A relationship is proposed between the critical depth D sub c and p sub c, or 1 sub 1. For overlayered stratum, experimental results have shown that the value of D sub c decreases rapidly with the value of the overload applied to the bearing stratum. It is shown that for long poles, the current rule of 3-5 diameters of penetration in the bearing stratum allows a mobilization of the full point resistance of the pile.
