For hypothetical <br /> lateral loading from the terminal toward the water,the furthest offshore pile row closest would be <br /> considered to be Row 1 in the table. Use linear interpolation to obtain reduction factors for pile spacing <br /> not shown on the table. <br /> Table 18 — LPILE Group Reduction Factors <br /> P-Multiplier(mn) <br /> Pile Center-to- Row 3 and <br /> Center Spacing Row 1 Row 2 Higher <br /> 3D 0.8 0.4 0.3 <br /> 5D 1.0 0.85 0.7 <br /> 8D 1.0 1.0 1.0 <br /> Note: D represents the pile outer diameter. <br /> Vertical Pile Capacity <br /> We reviewed the results from recent pile driving activities on the north end of the terminal,along with the <br /> existing information from the 1978 design drawings and the results of our field explorations.and used this <br /> information in our static analysis in order to assess the vertical capacity of driven piles. <br /> 19232-01 A <br /> December 6,2017 sus <br /> W.IRTCROWSER <br />
