针对裂缝性地层的裂缝发育方位问题，建立具有任意方位角的方位各向异性黏弹性本构关系。
This work establishes a new constitutive relation on the azimuthally anisotropic linear viscoelastic media with an arbitrary azimuthal angle for the fractured strata.
由于裂隙裂缝介质的空间展布是任意的，因而有可能通过研究不同观测方位的弹性波波场来研究这类介质。
Irregular fractured medium can be desirably ascertained by analysing the elastic wave fields which were observed in different positions.
