从地质力学到生物力学，饱和多孔介质的响应是许多领域的重要研究课题。Biot是第一个提出控制多孔介质中耦合流动和变形过程的基本方程的人。根据加载的性质和介质的特性，可以有不同的配方（完全动态、部分动态、准静态）。本文建立了平面应变条件下饱和和接近饱和多孔介质响应的解析解。不同配方的解决方案是根据非量纲参数开发的。研究了各种条件下的响应，并在参数空间中确定了各种公式的有效区域。本文还对几个重要问题所需的提法进行了评估。版权所有©2008 John Wiley & Sons， Ltd
The response of saturated porous medium is of significant interest in many fields ranging from geomechanics to biomechanics. Biot was the first to formulate the basic equations governing the process of coupled flow and deformation in porous media. Depending on the nature of loading vis‐à‐vis the characteristics of the media, different formulations (fully dynamic, partly dynamic, quasi‐static) are possible. In this study, analytical solutions are developed for the response of saturated and nearly saturated porous media under plane strain condition. The solutions for different formulations are developed in terms of non‐dimensional parameters. The response is studied for various conditions and the regions of validity for various formulations are identified in a parametric space. An assessment of the needed formulation for few important problems is also presented. Copyright © 2008 John Wiley & Sons, Ltd.
