摘要
基于饱和多孔介质理论,将土体视为液固饱和两相介质,研究分析了粘弹性饱和土体中圆形隧道洞的稳态响应问题,得到了隧道洞边界作用轴对称荷载时的径向位移幅值、径向应力幅值和孔隙水压力幅值的稳态响应解,研究了渗透系数、阻尼系数对圆形隧道洞稳态响应的影响。
Based on porous medium theory,the steady state response of a liquid-saturated circular tunnel is investigated,where the solid skeleton is modeled as a viscoelasticity.The steady state response amplitudes of radial displacement,radial stress and pore water pressure are obtained,and the effects of permeability coefficient and damping coefficient on the steady state response of the circular tunnel are simulated numerically.
