How to derive from poroelastic 3D equations to 1D Terzaghi equation?
Wed, 2010-06-30 07:15 - Xiaogai Li
Hi!
In the terzaghi equation, there is a constant M (some books call is elastic oedemetric coefficient).
Since the terzaghi equation is a special case for the general 3D biot equations under oedemetric testboundary conditions, does any book or material explain the derivation?
If I want to mode the terzaghi problem using 3D model in FE program, the M is known, then how to get thecorresponding values of young's modulus and poisson's ratio in order to give the same response from the 3D model?
Thanks for your attention. Any suggestions would be appreciated.

A problem
What is the poroelastic 3D equations ? please give some more information about it!
Poroelastic Media
Dear S.H. Zhu
Hope all is well with you.
You know, these days i'm working on fully coupled hydraulic fracturing propagation in poroelastic media but my poroelastic matlab code doesn't work proparely.
I've got to finish my Msc thesis as soon as possible.
would you please do me a favor and send me any 2D poroelastic media Matlab code you may have.
Best.
Rice's note may be helpful
Hi Mr Li.
I think you can find answer from the paper
J. R. Rice and M. P. Cleary, "Some Basic Stress-Diffusion Solutions for Fluid-Saturated Elastic Porous Media with Compressible Constituents", Reviews of Geophysics and Space Physics, 14, 1976, pp. 227-241.
and also the lecture note,
J.R. rice, asticity of Fluid-Infiltrated Porous Solids
They are both available from Professor James R Rice's webpage,

Hope it helps.
