Design of a Help Tool for the Evaluation of the Permeability of Saturated Soil

Abstract

The permeability of a soil represents the property of this soil to allow penetration by a fluid, the permeability in the saturated state (ks) of soils is an important parameter to determine before the design of geotechnical works, because it constitutes a factor determining factor in the calculation of the load-bearing capacity of soils. The models for predicting saturated permeability proposed in the literature are numerous (statistical models, empirical models, etc.), and the comparison studies between these models are also numerous; with the aim of facilitating such studies we have attempted to present an expert system which takes care of the evaluation of this parameter based on the methods of (Beyer 1981, Kruger 1992, Terzaghi 1981). Our expert system first allows the calculation of (ks) from the three models studied, as it also allows the comparison between the results of these models on the basis of calculation of the mean square error.
