Influence of Excess Pore Pressures on Axial Offshore Pile Response

摘要

The paper describes an analysis for taking account of the effects of excess pore pressures generated around a pile during cyclic axial loading. Consideration is given to the reduction in load capacity and pile head stiffness resulting from cyclic loading of typical offshore piles in a calcareous sediment. Factors which act to accelerate the rate f dissipation of excess pore pressures will also act to reduce the amount of degradation of load capacity and pile head stiffness. No account is taken of the possible effects of volumetric strains which develop in the soil near the pile during pore pressure dissipation.
