具有平行断裂和线状裂隙的介质中弹性波的传播M.SCHOENBERG 郭路平译文章用平行滑动界面模型模拟了由密集的线状大裂隙构成的断裂体系的性状。该模型含有各种断裂体系的各向异性:三斜(最常见的)、单斜、正交或横向同性等,因此可用3×3断裂体系顺应矩阵的形式表示断裂体系可夹入对各向异性的类型没有限制的各向异性弹性背景中。文章指出,计算断裂介质的长波长等效模量,至多需要2个3×3矩阵的反演。假定断裂大致是轴对称的(即横向各向同性断裂体系性质),且假定背景为各向同性的,那么所得的等效介质是横向同性的,并且断裂体系
The Propagation of Elastic Waves in a Medium with Parallel Fractures and Linear Fissures M.SCHOENBERG The parallel sliding interface model is used to simulate the behavior of a fractured system made up of dense linear fissures. The model contains anisotropy of various fracture systems: triclinic (the most common), monoclinic, orthogonal or transverse isotropic, etc. Therefore, the fracture system can be expressed in the form of a 3 × 3 fracture matrix. There is no limit to the type of anisotropy in the anisotropic elastic background. The article points out that calculating the long wavelength equivalent modulus of the fracture medium requires at most two 3 × 3 matrix inversions. Assuming that the fracture is approximately axisymmetric (ie, a transversely isotropic fracture system property) and the background is assumed to be isotropic, the resulting equivalent medium is transversely isotropic and the fracture system
