【摘要】 将桩—土系统中波的传播理论由弹性范畴推广到粘弹性范畴。提出桩土系统桩、土间相互作用与剪切梯度变化率有关,其阻尼波动方程实际上就是Kelvin固体的运动微分方程,从而引入Stokes波动方程,并用子波函数法对波动方程进行了求解。更多还原

【Abstract】 In this paper the theory of wave propagation in the pile-soil system is extended from the elastic category to the viscoelastic one.It suggests that the pile-soil interaction is related to shear gradient ratio and the equation of damping wave motion is in fact the differential equation of motion of the Kelvin solid.The Stokes wave motion equation is introduced and solved by using the method of wavelet function.更多还原
