Anisotropy in volume change behaviour of soils during shrinkage

摘要: It has been long recognised that some of the fundamental and engineering properties soils exhibit a certain degree anisotropy eventually dictates their directional geoengineering behaviours. Consideration importance volume change behaviour during shrinkage critical review literature suggests scopes for further research development better understanding in encountered soil shrinkage. In this paper, volumetric is depicted with theory geometry factor strains. A systematic investigation analysis on evolution factors strains several geomaterial samples evaporative dewatering reported herein. theoretical framework evaluating cylindrical specimen undergoing progressive moisture loss described paper. Furthermore, based experimental data, specimens differing terms gradational properties, size, boundary condition pore fluid salinity are evaluated discussed detail accordance framework. Linkages between process, shrinkages also analysed to underpin usage characterise
