Abstract: Based on nonlinear finite element calculation, the influence of size effect of pile on load-bearing behaviour of rock-socketed pile is analyzed. The results show that the rock-socketed depth-diameter ratio decreases with increasing diameter of pile while other conditions are invariable, bearing capacity of pile takes on increscent trend due to chiefly bearing pressure of pile tip enhancing. Additionally, socketed depth influences the bearing properties, the shorter socketed depth, the more strength load-bearing of pile tip. So the bearing capacity can be enchanced by enlarging pile diameter in course of design.

Key words: rock-socketed pile, load-bearing behaviour, size effect, finite element method
