Abstract EN
Based on the mixture theory and previous work, the governing equation of the rotary vibration of rigid friction pipe pile in unsaturated soil is established.
The analytical solution of this equation can be used to analyze the displacements and the complex stiffness of rotary vibration.
The results show that the contribution to stiffness is as follows: solid < liquid < gas; and the contribution to rotational impedance is as follows: solid > liquid > gas.
In addition, when the fluid permeability coefficient decreases, the stiffness decreases and the rotational impedance increases, but the influence is not obvious (especially the gas permeability coefficient).
Four different kinds of degradation problems are also presented.
Relevant conclusions can provide reference for engineering application.
