Soil Variable Analysis of Spiral Pile-Driven Process Simulation

Abstract

Pile driven-operations is an important means to control floods, anti-flood spiral pile is a kind of flood control equipment which is lightweight, high work efficiency and low labor intensity. It is important to research the soil variables to further clarify the mechanism of pile-soil interaction in driven process. Soil constitutive model was built as the SPH particles; pile-driven process was simulated by dynamics software. By tracing the SPH (Smoothed Particle Hydrodynamics) particles, contrasting and analyzing the movement of soil particles at different times and depths because of friction, extrusion, and shear effect of pile were achieved. The mechanism of pile - soil interaction in the driven process was clarified by analyzing and comparing the simulation results, which make up the lack of theoretical analysis and experimental methods. It will provide useful suggestions on the design of spiral pile and reducing the secondary damage to dam.
