IN-SITU TESTING METHODS
(SPT-Pile Capacity Calculations)
Calculate the ultimate bearing capacity for clean sand material by using Schmertman (1974), Meyerhof (1976), and Biraud (1985) methods, and then estimate the ultimate bearing capacity for a suitable design by using these results together.
Given parameters for pile:
Diameter of the driven pile: 1.0 m
Length of the driven pile: 20 m
Average
N_(60)
value for shaft resistance: 25
Average
N_(60)
value for end bearing capacity: 32
