岩石的波阻抗岩石的波阻抗Iimpedance of rock yansh一de因ZLJkang岩石的波阻抗(impedanee of rock)岩石中的纵波速度与岩石密度的乘积。它表明应力波在岩体中传播时，运动着的岩石质点产生单位速度所需的扰动力。它反映了岩石对动量传递的抵抗能力。波阻抗大的岩石往往比较难于爆破。某些岩石的波阻抗值见表。界面两侧的波阻抗变化，对波的能量传播有很大影响。当两侧波阻抗相等时，入射波的能量全部透过界面传到另一侧。界面两侧波阻抗不等时，无论增大或变小，人射波的能量都不能全部透过界面传到另一侧。界面前方的波阻抗为零时称自由端反射，反射波和人射波的幅度大小相等符号相反;当界面前方的波阻抗为无限大时，称固定端反射，反射波的大小、符号都与入射波相同，透射波则是入射波的两倍。 岩石的波阻抗值讨绷片 (宋守志)
