(14,700 ft). The site at 5.5 km (18,000 ft) is below the CCD; there- 

 fore, the soil is probably pelagic clay. Typical properties are given by 

 Figure 2-7. A mid-range value is chosen as adequate factors of safety 

 will be included later. 



7.1.2 Hazardous/Unusual Conditions 



None of the examples in paragraph 2.4 apply. The site does not 

 present any hazardous/unusual conditions. 



7.1.3 Penetration 



Penetration into cohesive soils is covered by paragraph 3.1. A 

 tabulation of penetration depths for each CEL propellant-embedded 

 anchor for each typical soil profile of paragraph 2.3.4 is given in 

 Table 3-1. From Table 3-1, penetration of the 20K anchor clay fluke in 

 the lower bound and upper bound pelagic clay is found to be 14.3 

 meters (47 ft) and 11.3 meters (37 ft), respectively. For a mid-range 

 soil profile, D is midway between these values, or 12.8 meters (42 ft). 



7.1.4 Fluke Keying 



Using Equation 4-1 from paragraph 4.1: 



D = D - 2 L (4-1) 



P 



= 12.8 - (2)(0.9) 

 = 11m (36 ft) 



7.1.5 Static Holding Capacity 



The short-term static holding capacity in cohesive soil is calculated 

 from Equation 5-1 in paragraph 5.1.1:
