Improvement of the Mechanical Characteristics of Soil Contaminated with Lubricant Oil-Cal Mix

摘要

The demographic and technological evolutions are confronted by geo-environmental problems.When chemicals or contaminants are introduced into the soil,they affect the soil properties such as the grain size curves,the structure,compressibility and stress-strain behaviour.However,the classical soil mechanics models and methods to incorporate the effects of contaminants have not yet been developed.In this study the proposed analysis of geotechnical structure involving effect of chemicals contaminants such as a wasted lubricate oil with lime on the main factors affecting the behaviour of a compacted soil mass and the analysis of a granite residual soil involving effect of the moisture on the compressibility and shear stress behaviour.These concepts can improve the use of these kinds of soils in geotechnical engineering works.
