Finite difference analysis of one dimensional consolidation of homogeneous clay layer

Abstract EN

This research presents an explicit finite difference solution for the one-dimensional consolidation of a homogeneous clay layer with permeable top and impermeable bottom.

A computer program was written in BASIC to deal with this problem.

The comparison of the numerical solution developed with the corresponding solution by Craig (2007) for the case of non-uniform initial excess pore-water pressure distribution showed excellent agreement.

The computer program was written so as to deal with one dimensional consolidation of one layer clay for whatever case need to be studied.

Different hydraulic boundary conditions, different distributions of initial access pore water pressure, and different properties of soil can be easily studied using this program.

The researchers and students will not find any difficulty to find the degree of consolidation of any type of soil layer especially when they run the computer program which will take the pore water pressure for all meshes and time needed very fast by using finite difference technique.
