Driven piles in clay—the effects of installation and subsequent consolidation

摘要: This paper describes the results of numerical analysis effects installing a driven pile. The geometry problem has been simplified by assumption plane strain conditions in addition to axial symmetry. Pile installation modelled as undrained expansion cylindrical cavity. excess pore pressures generated this process have subsequently assumed dissipate means outward radial flow water. consolidation soil studied using work-hardening elasto–plastic model which unique feature allowing strength change water content changes. Thus it is possible calculate new intrinsic at any stage during consolidation. In particular long-term shaft capacity pile may be estimated from final effective stress state and adjacent A parametric study made effect past history soil...
