  • There has been not enough study on anti-draw bearing properties of rock-socketed pile. The influence of pile diameter, pile length and socketed length on uplift bearing properties of rock-socketed pile is analyzed by using methods of grey system theory and non-linear finite element analysis. The results indicate that pile diameter has the strongest influence on uplift hearing capacity of rock-socketed pile, on which socketed length has much lesser influence while pile length has the weakest influence. And pile diameter and rock-socketed length shows a non-linear positive relationship with axial uplift secant stiffness of pile in certain extent, and pile length shows a non-linear negative relationship.
