2 points End-bearing piles are to be constructed in a site with soil stratigraphy as follows (starting from the ground surface) 3 m layer of new fill, followed by 9 m layer of soft clay, followed by a deep layer of dense sand. The GWT is 2m below the ground surface. When we calculate the ultimate capacity of the pile, we should O a. Use the frictional capacity from all the layers in downword direction b. Use the frictional capacity from all the layers in upward direction. Oc. Use the frictional capacity from the fill layer and the soft clay layer in downward direction but that from the dense sand layer in upward direction. d. Use the frictional capacity from the fill layer in downward direction but that from the soft clay layer and dense sand layer in upward direction. e. Use the frictional capacity from the the soft clay layer in downward direction but that from the fill layer and dense sand layer in upward direction
