A Performance Study of Hollow Pile Under Lateral-Dynamic Load Using the Method of Composite Stiffness Principle and Biparameter
Abstract:In order to compare the similarities and differences between hollow pile and solid pile when they are subjected to dynamic loads at the top of pile, the dynamic performances of hollow pile and solid pile under lateral dynamic load were analyzed using composite stiffness principle and double-parameter method in this paper. The deflection, bending moment, rotation angle, shear and soil resistance were respectively calculated for solid pile and hollow pile with the same diameter and with the same sectional area by changing the cross-section shape and size of pile. The results of this research show that the hollow pile has many advantages compared with solid pile. For example, the deflection and rotation angle at the top of hollow pile is smaller, and the bearing capacity per unit volume of hollow pile is higher. The research of this paper provides a theoretical basis for the application of hollow pile in engineering.
