| Abstract |
The current theories on pile driving vibration are based on localized theories. Therefore, the
objective of this paper is to consider the gradient variation of porosity along the depth in relation to the
depth of pile driven into the soil layer in the framework of non-local theory. The ramming energy
parameter is introduced to improve the model of gradient variation of porosity along depth. The coupled analytical solution is proposed of surface vibration induced by steel pipe pile driven into nonuniform saturated soil layer by the porosity is coupled with density, shear modulus, Lamé constant and
permeability coefficient, and coupling the tamping energy parameter into Eringen’s nonlocal theory
and Biot’s theory of saturated porous elastic medium, and combining the mass conservation equation,
momentum balance equation, and effective stress principle. Analysis the change rule of impact energy
attenuation degradation and the influence of surface vibration deformation during the process of PHC
pile driving into non-uniform saturated soil layer. The results of the study show that the influence of
soil uneven gradient parameter on soil parameters is greater than that of energy parameter. Pile driven
into the non-uniform soil layer at any depth location, uneven gradient parameters and energy parameters under the increase, the horizontal amplitude of surface vibration, vertical amplitude decreases.
However, the horizontal amplitude and vertical amplitude of surface vibration increased with the
increase of soil skeleton geometry parameter. The analysis shows that the energy parameter has the
greatest influence on the horizontal and vertical amplitudes, the soil skeleton geometry parameter has
the second greatest influence on the horizontal and vertical amplitudes, and the non-uniform gradient
parameter has the least influence on the horizontal and vertical amplitudes. The results of the study
can assess the problem of surface vibration response induced by pile driving construction, but the theory is a result of the study carried out in the framework of nonlocal elasticity theory, which still needs
further improvement. |
