Engineering News Formula for Pile Load Capacity
The Engineering News formula is a widely used method for estimating the load carrying capacity of piles. It is based on the energy of the pile driving hammer and the resistance of the soil.
Formula:
Load carrying capacity = (2E) / (A + S)
Where:
E = energy of the hammer (in kg-m)
A = area of cross section of the pile (in sq. cm)
S = set per blow (in cm)
Calculating the Load Carrying Capacity
Given:
Weight of the hammer (W) = 1800 kg
Free fall distance (h) = 1.00 m
Penetration with last blow (S) = 5 mm = 0.5 cm
To calculate the energy of the hammer (E), we use the formula:
E = W x h
E = 1800 x 1.00 = 1800 kg-m
The area of cross section of the pile (A) is not given. However, we can assume a typical value for the area of a concrete pile, which is around 1000 sq. cm.
Using these values in the Engineering News formula, we get:
Load carrying capacity = (2E) / (A + S)
Load carrying capacity = (2 x 1800) / (1000 + 0.5)
Load carrying capacity = 3600 / 1000.5
Load carrying capacity = 3.598 tonnes or 3598 kg
Therefore, the load carrying capacity of the pile according to the Engineering News formula is approximately 3.6 tonnes.
Conclusion
The load carrying capacity of a pile depends on various factors such as the type of soil, the depth of the pile, the diameter of the pile, and the energy of the hammer used for driving the pile. The Engineering News formula is a useful tool for estimating the load carrying capacity of piles based on the energy of the hammer and the resistance of the soil.
