Option for Improving the Deformation Behaviour of Compacted Clay Barriers Subjected to Differential Settlements
Lining systems render a significant role in ensuring that waste materials are safely separated from the environment. Despite the advent of modern lining systems, compacted clay barriers or liners are regarded as one of the very significant components of lining system and are being used as a waste containment system in landfills which require insignificant infiltration. Compacted clay barriers m...
متن کاملCompacted Urban Soils and their Remediation
The effects of urbanization on soil structure can be extensive. Infiltration of rain water through soils can be greatly reduced, plus the benefits of infiltration and biofiltration devices can be severely jeopardized. Our research group (along with others), have been studying disturbed urban soils for several decades, both in the laboratory and in the field. The effects of compaction on infiltr...
متن کاملSwelling Characteristics of Compacted, Expansive Soils
Abstraet-The limitations of existing methods for the prediction of swelling behavior of compacted softs are examined. Both the purely theoretical approach and the purely empirical approach are found to be inadequate. The present study is based on a semi-empirical approach in which a model of swelling behavior is developed leading to equations relating swelling potential or swelling pressure of ...
متن کاملFabric and Deformation in Granular Materials
The paper presents results of numerical experiments on a large assembly of smooth circular disks. The assembly was subjected to quasi-static biaxial loading at small to moderate strains by using the Discrete Element Method. Unlike the usual particle-based and coordination number approaches, the fabric was locally measured in relation to the shapes and orientations of voids. Deformation was meas...
متن کاملMechanical interaction between swelling compacted clay and fractured rock, and the leaching of clay colloids
We consider the interaction between a saturated clay buffer layer and a fractured crystalline rock engineered disturbed zone. Once saturated, the clay extrudes into the available rock fractures, behaving as a compressible nonNewtonian fluid. We discuss the modelling implications of published experiments carried out in Sweden and more recently in Japan. Extrusion is halted either when the advanc...
