摘要：This paper presents a collection of finite element procedures to model seismic wave propagation at the macroscale taking into account the ef- fects caused by heterogeneities occuring at the mesoscale. For this purpose we first apply a set of compressibility and shear experiments to representative samples of the heterogeneous .uid saturated material. In turn these experiments yield the e.ective coe.cients of an anisotropic macroscopic medium employed for numerical sim- ulations at the macroscale. Numerical experi- ments illustrate the implementation of the pro- p osed methodology to model wave propagation at the macroscale in a patchy brine-CO 2 saturated p orous medium containing a dense set of parallel fractures.
