36 Piles are arranged in a square pattern which is embedded in the clayey soil. The shear strength at the base of the pile is 200 kN/m2 and the average shear strength over the depth of the pile is 130 kN/m2. If the Diameter and length of the pile are 0.4 m and 12 m respectively, the safe load that the pile group can carry will be _______ kN. Assume, centre to centre spacing between the pile = 0.8 m, Adhesion factor (α) = 0.50 and Factor of safety = 3

B = (n – 1)s + d
B = (6 – 1) × 0.8 + 0.4
B = 4.0 + 0.4 = 4.4 m
Ultimate load carrying capacity of single pile:
Qup = qb Ab + qs As
Qb = base resistance of pile = 9c
c = cohesion at base of the pile
ϕ = 0° (clay)
Sbase = c = 200 kN/m2
qs = average skin friction resistance
Qup = 1206.37 kN
Ultimate load carrying capacity of pile group
= 9 × 200 × (4.4)2 + 0.5 × 130 × 4 × 4.4 × 12
Qug = 48576 kN
Safe load on pile group = 
So, safe load on pile group will be lesser of two. Hence safe load = 14476.44 kN
So, safe load on pile group will be lesser of two. Hence safe load = 14476.44 kN

AF) = 0.7, and Shape factor (SF) = 0.55.
The safe load that a single pile can carry can be calculated using the formula:
Safe Load = (Average Shear Strength) x (Area of the Pile Base)
The area of the pile base can be calculated using the formula:
Area of the Pile Base = π x (Diameter/2)^2
Plugging in the given values:
Area of the Pile Base = π x (0.4/2)^2 = 0.1256 m^2
Safe Load (Single Pile) = 130 kN/m^2 x 0.1256 m^2 = 16.32 kN
To calculate the safe load that the pile group can carry, we need to consider the interaction between the piles. The group efficiency factor (G.E.F.) can be calculated using the formula:
G.E.F. = (1 + AF x SF) / (1 + AF)
Plugging in the given values:
G.E.F. = (1 + 0.7 x 0.55) / (1 + 0.7) = 0.8718
The safe load that the pile group can carry can be calculated using the formula:
Safe Load (Pile Group) = G.E.F. x (Number of Piles) x (Safe Load Single Pile)
Plugging in the given values:
Safe Load (Pile Group) = 0.8718 x 36 x 16.32 kN = 534.85 kN
Therefore, the safe load that the pile group can carry is approximately 534.85 kN.
The safe load that a single pile can carry can be calculated using the formula:
Safe Load = (Average Shear Strength) x (Area of the Pile Base)
The area of the pile base can be calculated using the formula:
Area of the Pile Base = π x (Diameter/2)^2
Plugging in the given values:
Area of the Pile Base = π x (0.4/2)^2 = 0.1256 m^2
Safe Load (Single Pile) = 130 kN/m^2 x 0.1256 m^2 = 16.32 kN
To calculate the safe load that the pile group can carry, we need to consider the interaction between the piles. The group efficiency factor (G.E.F.) can be calculated using the formula:
G.E.F. = (1 + AF x SF) / (1 + AF)
Plugging in the given values:
G.E.F. = (1 + 0.7 x 0.55) / (1 + 0.7) = 0.8718
The safe load that the pile group can carry can be calculated using the formula:
Safe Load (Pile Group) = G.E.F. x (Number of Piles) x (Safe Load Single Pile)
Plugging in the given values:
Safe Load (Pile Group) = 0.8718 x 36 x 16.32 kN = 534.85 kN
Therefore, the safe load that the pile group can carry is approximately 534.85 kN.
