Rock resistance of bored piles socketed into rock
In view of the large movement required to mobilize the bearing resistance of bored piles and difficulty in base cleaning, the bearing resistance often ignored in current design practice that will result in excessive rock socket length. Many attempts have been made to correlate the bearing resistance...
