CORRELATIONS BETWEEN THE PHYSICO-CHEMICAL PROPERTIES AND THE MECHANICAL CHARACTERISTICS OF COMPRESSIBLE SOILS

RELATIONS ENTRE LES PROPRIETES PHYSICO-CHIMIQUES ET LES CARACTERISTIQUES MECANIQES DES SOLS COMPRESSIBLES

This report covers a study of some forty soils ranging from muds to peats, analysed by methods based on sedimentology, chemistry, electronic microscopy, and physico-chemistry. The objective of the physico-chemical analysis was two-fold: (1) to improve knowledge and mastery of the mechanical behaviour of these types of soil; and (2) to establish a correlation between the parameters of long and costly tests, and those characteristics which were easily measurable. The sedimentology analyses provided information on the workability and textural characteristics of the soils. These tests showed the damaging influence of organic matter (humic colloids) on the mechanical behaviour of sedimentary soils. This effect is as strong again as the soil is poor in mineral colloids. It is therefore imperative to detect the presence not only of organic humus, but also of colloidal clay such as montmorillonite. Correlations have been shown to exist between compressibility and certain textural parameters, and between cation exchange capacity and the plasticity index test. Finally, a tentative textural classification of these soils is proposed. /TRRL/
