在将孔隙流体考虑为可压缩的且固相骨架具有线性粘弹性态的同时,本文研究了束缚空气对弹性波在饱水土体中传播的影响。结果表明,甚至当液相为不可压缩时,由于束缚空气的存在,饱水土体中亦存在着两种P波。数值算例指出,束缚空气的存在将使P波速度降低而使其相应的阻尼常数增大,但对S波却无影响。 While considering the pore fluid as compressible and the solid-phase framework has a linear viscoelastic state, the influence of bound air on the propagation of elastic waves in saturated soil is studied. The results show that even when the liquid phase is incompressible, there are two P waves in the saturated soil body due to the presence of bound air. Numerical examples show that the presence of bound air will reduce the P-wave velocity and increase its corresponding damping constant, but it has no effect on the S-wave.
