Bearing Capacity of Piles in Soft Clay Underlaid by Cohesive Frictional Soil

By using the axisymmetric quasi-lower bound finite-element limit analysis, the bearing capacity factors Npc and Npγq have been computed for axially loaded piles, with the shaft embedded in a fully cohesive soil medium and the tip placed over cohesive frictional soil strata. The results were obtained for various combinations of L/D, ϕl, and cl/cu; the subscripts l and u refer to lower and upper soil strata, respectively. The factors Npc and Npγq increase continuously with increases in L/D and ϕl; the rate of increase of Npc and Npγq with L/D, however, decreases with an increase in L/D. For cl/cu>100, the factor Npc hardly depends on L/D.
