Relative Embedment Depth, D/B 



Figure 5-1. Short-term holding capacity factors for cohesive soils (from Beard, 1979). 



The soil cohesion, c, of Equation 1-1 becomes the undrained shear 

 strength, s , for this type of loading'. The values of N are given in 

 Figure 5-1 as a function of relative fluke embedment depth, D/B. The 

 values of f have been recommended by Valent (1978) as 0.8 for terrige- 

 nous clayey-silts and silty-clays, 0.7 for pelagic clays, and 0.25 for 

 calcareous ooze. This factor accounts for soil disturbance from fluke 

 penetration and keying . The validity of f = . 25 for calcareous ooze is 

 in doubt, as it suggests a factor of 4 loss of soil strength. However, 

 until data supporting a higher value are available, its use is recom- 

 mended. A, B, and L are anchor fluke parameters.
