| 摘 要： | 采用描述地下流体饱和孔隙介质中弹性波与电磁场耦合现象的Pride方程组,利用Helmholtz分解,求解了非均匀震电耦合平面波解,推导了流体饱和孔隙介质中传播的非均匀震电平面波的能流表达式,讨论了非均匀震电平面波的能量特征.结果表明,非均匀震电平面波的平均能流在传播矢量和衰减矢量构成的平面内传播,伴随电磁场对纵波模式的能流没有贡献.当动电耦合系数为0时,震电平面波的能流表达式可退化为Biot弹性波的能流表达式。

| Abstract: | In fluid-saturated porous media elastic waves and electromagnetic fields are coupled due to relative flow between fluid and solid phases.Based on Pride equations,inhomogeneous seismoelectric plane waves are given;and the expressions of energy flux for those waves in fluid-saturated porous media are obtained with the Helmholtz's method;energy characteristics of inhomogeneous seismoelectric plane waves are discussed.It is shown that the mean energy flux propagates in the plane of the propagation vector and th... |
