| الوصف: | Theory of propagation of elastic waves in porous media has extensive application in many important areas, e. g. geophysical exploration, earthquake engineering, and geotechnical dynamics. Elastic waves in porous media are affected by medium properties e. g. porosity, permeability, and fluid viscosity, therefore, research of propagation characteristics of wave fields could be helpful to the analysis and determination of media properties. The Luco-Apsel-Chen (LAC) generalized reflection and transmission method has already affirmed its stability, efficiency, and wide application scope in the research of synthesis of theoretical seismogram. Based on Biot theory and aiming at three-dimensional (3D) stratified porous media, we use the LAC generalized reflection and transmission method to derive an integral expression of half-analytical solution for elastic waves, which could be used to efficiently and accurately compute the theoretical elastic wave fields in porous media by numerical method. This integral expression provides an alternative way for the theoretical research and numerical simulation of propagation characteristics of wave fields in 3D stratified porous media. ; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000338396900020&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Test ; Geochemistry & Geophysics ; SCI(E) ; EI ; 中文核心期刊要目总览(PKU) ; 中国科技核心期刊(ISTIC) ; 中国科学引文数据库(CSCD) ; 2 ; angelinaer0922@gmail.com; renhx@ustc.edu.cn ; 6 ; 1891-1899 ; 57 |
