8. Design of Coastal Structures
293
B = diameter of the pile, ki is Terzaghi’s modulus of subgrade reaction
as determined from load deflection measurements.
ki = 27 MN/m3 (for stiff clay)
MS (âM=8-8MN/m2
For soil (clay):
Stiffness factor R -
' El 1 *
J^hB
503.68 1 *
(8.8)(0.61)_
R = 3.11 m
Then the condition to find the behaviour of pile,
L — embedded pile - 20 m
L > 3.5R
L > (3.5)(3.11)
20 m > 10.885.
Condition satisfied.
Then this is a long pile.
