饱和冻土中弹性波的传播特性
Propagation characteristics of elastic wave in saturated frozen soil
摘要
Abstract
With the application of continuum theory of mixture, which takes the three-phase media, including grains, fluid and ice into account, the dispersion equations of body waves are established for saturated frozen soil by considering Bishop's effective stress formula. The equations are described with skeleton displacement, pore water displacement, pore water pressure and pore ice pressure. The analytical expressions of wave velocity and attenuation are deduced. The effects of frequency and the parameters of saturated frozen soils on the velocity and attenuation of three kinds of body waves (P1 wave, P2 wave and S wave, respectively) are investigated by using numerical method.关键词
