横观各向同性饱和介质非轴对称动力响应分离变量解
Separation of variables solution of non-axisymmetrical dynamic response of transversely isotropic saturated porous media
摘要
Abstract
Firstly ,this paper transforms the Biot’s wave equations of transversely isotropic saturated elastic media under the excitation of non‐axisymmetrical simple harmonic into a form w hich can be solved suitably by separation of variables .Secondly ,the general solutions of Biot’s equations and the analytical expression of porous media displacement and stress components can be derived using the separation of variables .Finally ,it also gives numerical results of the surface vertical displacement of half‐space trans‐versely isotropic and poroelastic media under the surface vertical harmonic loads .It also comes to a con‐clusion that the load has no effect on the area outside 30 times the radius of the loading area .It demon‐strates the accuracy and applicability of the present approach .关键词
