Archive image from page 17 of Determination of mooring load and. Determination of mooring load and transmitted wave height for a floating tire breakwater . determinationofm00gile Year: 1979 When e, the lever arm of the load applied above the firm bottom, is zero the equation may be solved directly for required pile length as: I = U dkJ 1/2 (8) This method of analysis has been predicated on the maximum bending moment in the loaded pile not exceeding the piling sections maximum yield moment. This is considered a safe assumption for the typical short anchor pile problem. When the foundation soils at the breakwater site are clay, the method in Broms (1964a) is used for determining the ultimate lateral resistance of a rigid-pile anchor under lateral load. As before, the pile is assumed to rotate without bending around a point in the lower half of the pile (see Fig. 6). The length of pile required is e++f+q (9) (See Fig. 6 for definition of terms.) The maximum moment occurs at (f + ) below the firm soil level where f = (10) 9 cuD The term c is the undrained cohesive strength of the clay. Care should be taken in the determination of the value of c to reflect the dynamic nature of the lateral load. The length, q, is the length of Figure 6. Failure mode for a short-rigid pile in cohesive soil (after Broms 1964a).
