5 Questions
What is the main cause of frictional resistance, f, during pile driving?
The pile installation method
What is the approximate range of the critical depth, L', where unit skin friction remains constant?
15 to 20 pile diameters
How does the unit skin friction vary with depth during pile driving?
Unit skin friction increases more or less linearly to a depth of L' and remains constant thereafter
What is the zone of sand densification caused by pile driving?
2.5 times the pile diameter
What is a conservative estimate for the critical depth, L'?
20 pile diameters
Test your knowledge on the factors influencing frictional resistance during pile driving and soil densification around the pile. Explore the nature of pile installation and variation of frictional resistance in the field.
