Abstract

This paper is concerned with the evaluation of the shape factor by means of the electric analogy. This factor is used for the determination of the soil permeability from field tests. After a description of the experimental device, we present the methodology followed for the determination of the shape factor. Then, we study the influence, on this factor, of some parameters such as the position of the infiltration cavity in the soil layer and the presence of an obstacle or of heterogeneity near the cavity. 1 Introduction Design and calculation of civil engineering substructures and environmental facili- ties depend strongly on the soil permeability. Its d
