| 摘 要： | 给出了有限二维饱和多孔介质因点汇诱发的Biot固结的一个解析解。其中假设多孔介质为均匀各向同性和线弹性,假设孔隙压力场符合第1类边界条件,数学模型采用可压缩多孔介质模型。利用傅里叶和拉普拉斯变换及相应反演获得了双重无穷项级数和形式的精确解。然后特别探讨了定流量点汇诱发的稳态解析解,并用文献现有解析解进行了验证。所提出的解析解适合于验证数值解,并可用于深入分析有限二维多孔介质的流-固耦合行为。 |

| Abstract: | An analytical solution is proposed for the Biot's consolidation theory within a finite two-dimensional(2D),isotropic,homogeneous,and fluid-saturated poroelastic media due to a point sink when the pore pressure is prescribed on the boundary.The analysis is based on compressible porous media models.Fourier and Laplace transforms and related inversions are implemented;and the exact solutions in the form of double summations of infinite series are obtained.In particular,the steady-state analytical solution due ... |
| Keywords: | finite 2D poroelastic media Biot's consolidation finite sine and cosine transforms analytical solution |
