A drilled shaft in a medium sand is shown in Figure P10.9. Using the method proposed by Reese and O'Neill, determine the following:
a. The net allowable point resistance for a base movement of 25 mm
b. The shaft frictional resistance for a base movement of 25 mm
c. The total load that can be carried by the drilled shaft for a total base movement of 25 mm
Assume the following values:
L 5 12 m g 5 18 kN/m3
L1 5 11 m f9 5 388
Ds 5 1 m Dr 5 65%smedium sandd
