A drilled shaft constructed in medium sand is shown in the figure below. Given information is: y = 18 kN/m', 6' 38°. Sand is medium-density sand, and the average standard penetration number (Noo) within 2D, below the drilled shaft is 19, 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. 1 m 11 m 12 m

Question
Transcribed Image Text:A drilled shaft constructed in medium sand is shown in the figure below. Given information is: y
= 18 kN/m', '= 38°. Sand is medium-density sand, and the average standard penetration number
(N60) within 2Ds below the drilled shaft is 19. 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.
