Abstract

A method for representation of soil media and boundary conditions in a cross section of ground layers is presented. The method is based on algorithms used in computer graphics, called raster scan algorithms, RSA. The method may be applied to various soil mechanics solutions, especially slope stability problems. In this article it is applied to steady state two-dimensional groundwater flow. Seepage equations are modified to finite difference equations that can be used with the raster scan algorithms. The method is used to determine total head, pressure head and flow rates at any soil point (pixel). Most of the characteristic problems in groundwater flow are easily treated with RSA method such as, anisotropy, multi soil layers, pockets of special soils, different boundary conditions, confined and unconfined flow, and flow to wells.

Verifications included flow around a sheet pile, flow through earth dam and flow under a concrete dam. RSA method shows very promising to solve geotechnical problems efficiently.
