The allowable downward capacity of a 14HP102 pile is 100 tons per pile. This value ignores <br />the friction in the fill material and includes a factor of safety of 3. The allowable downward <br />capacity may be increased by 15 percent for each pile in a group of 4 or more piles. The <br />allowable uplift capacity is 30 tons per pile. This value excludes the weight of the pile and <br />includes a factor of safety of 2. <br />Settlement of the pile is estimated to be less than 114 inch. The settlements are expected to <br />be elastic in nature and will occur essentially simultaneously with the application of load. <br />5.3.2 Ljt2mLj gAjjJU <br />Lateral load camities of the piles will be proportional to the allowable deflections. An <br />allowable lateral load of 10 kips is estimated for a deflection of 1 /2 inch. This capacity is for the <br />weak axis of the pile, and may be increased by 50 percent for the strong axis. <br />If a pile is pre -drilled prior to driving, for example to reduce downdrag (tee Section 5.3.3), <br />its lateral load capacity should be ignored. In this cue lateral loads can be resisted solely by <br />Passive resistance of soil against the pile cap. Passive pressures may be es irnated using soil <br />Parameters previously recommended in Section 5.2.2 for caissons. <br />5.3.3 D o ndug <br />Downdrag loads may be experienced by piles located within the organic -rich am identified <br />on Plate 9. The downdrag loads would result from the long term decomposition and compression <br />of organic materials accompanied by settlement of the overlying fill soils. Downdrag loads will <br />be highest at locations where the highly organic pockets am located deepest within the fill layer. <br />We estimate that downdrag loads of up to 45 tons per pile may occur. This load will be in <br />addition to that imposed by the proposed structure itself. Since the distribution of the highly <br />organic pockets within the fill layer appears to be quite variable, we recommend that all piles <br />within the organic rich zone be designed for the above mentioned downdrag load magnitudes. <br />8-005-Oe69S-016\a0407e0.np <br />00695-SM-016 13 <br />
