Abstract:

Comparative test study of anti-pulling property of X-shaped pile and circular section pile with constant section is carried out in the self-developed large-scale soil test model chamber. The distributions of axial forces, lateral frictions and displacement are analyzed. the lateral surface of The X-shaped pile is 31.5% greater than the circular section pile; but the distributions of lateral friction force along pile shaft are almost the same, which consist of two different zones, raising zone and decay zone. The friction force is fully exerted from 1.5 m to 3 m away the pile head, and the minimum value and peak value of X-shaped pile in the area are larger than circular section pile. Under the same settlements, the lateral friction force of X-shaped pile is greater than circular pile. The results show that the ability of X-shaped pile to resist uplift force is 16.7% higher than that of the circular pile.

Key words: X-shaped concrete pile, model test, anti-pulling test, pile lateral friction
