1 MPa or 100 kPa. 6qc Drained loading Fully plugged piles develop half of the end resistance of closed-ended piles given by Equation H1 after a pile head displacement of D/10. Unplugged piles sustain end bearing on the annular area of steel only. Base resistance is equal to average CPT end resistance at the founding depth. 6 for drained conditions. No specific allowance is made for the shear stresses developed on the pile’s inner wall. The alternative methods outlined in Table 6 represent provisional best estimates and the tentative plugging criterion given in Step J1 is wholly empirical.
These capacities might be available in cases where additional loads were to be applied, or the piles re-used in a new or modified project development. The reuse of existing foundations is becoming more commonplace as sites become more congested and space for new piles becomes restricted. In this respect, increases in driven pile capacity with time could provide the justification for higher working loads or else deliver a larger factor of safety against failure. The re-assessment of the Leman BD North Sea platform foundations is described by Jardine et al.
When the YSR is low and the soil is sensitive, large gains may be expected over the pore pressure equalisation stage (set-up), while insensitive high YSR clays can even show reductions in capacity with time. Such changes are correlated closely with the variations in σ'r with time. Figure 30 summarises the σ'r trends seen in the ICP experiments, plotting the trends for the values of K = (σ'r /σ'v0) divided by their final Kc values. Points to note are: 1. K increases steadily during equalisation in the low YSR Bothkennar and Pentre clays.
