The Effects and Vertical Bearing Capacity of Two Jacked Model Piles in Sand

The effects and vertical bearing capacity of two jacked piles in sand are still not well understood, the mechanism adjacent pile’s uplift caused by jacking pile a double system is especially unclear, but these facets important to stability pile. In this paper, series tests performed on model sand, where influences length driving speed were studied. results revealed that mainly relation influenced speed. horizontal displacement top first during installation post-jacking was difference stress state between side face its back side, which also involved. radial increased nonlinearly with depth under different lengths gradually converged passive earth pressure. ultimate approximately twice single pile, ratio final pressure 1.04.
