For the drilled shaft described in Problem 10.1, what skin resistance would develop in the top 6 m, which are in clay ?

Transcribed Image Text:A drilled shaft is shown in Figure P10.1. Determine the net allowable point bearing
capacity. Given
Ye = 15.6 kN/m³
Ys = 17.6 kN/m³
6' = 35°
D, = 2 m
D = 1.2 m
Lj = 6 m
L = 3 m
Factor of safety
C, = 35 kN/m²
