Abstract Compacted clays are commonly utilized as landfill liners due to their impermeable properties, however, the availability of natural clay soil may be difficult or prohibitively expensive in some regions thanks expense transportation, local regulation. As an alternative hydraulic barrier, a compacted mixture sand with low percentage bentonite (6% 14%) was used. The purpose this research i...

Finite difference method (FDM) has been adapted herein to analyze the performance of fully saturated clay barrier by using 1-D contaminant transport model to predict migration of two typical contaminant species, namely, sodium and chloride from the leachate of municipal waste landfill. The constructed clay liner media compacted in different lifts or the natural clay deposit beneath the landfill...

A laboratory investigation on a scaled model of a landACT: l ti n a scaled o l f ­ fill liner was conducted to provide data regarding the occurrence l i e e and extent of desiccation cracking of prototype liners. The crack t t of desi t e li rs. intensity factor, CIF, was introduced as a descriptor of the extent of t f , , as i tr as f the extent of surficial cracking. CIF is defmed as the rati...

Needle-punched geosynthetic clay liner (NPGCL) has been widely used in landfills. The internal strength of the GCL changes with temperature variation, which affects its application A large-scale temperature-controlled direct shear apparatus was developed to study characteristics affected by temperature. dependent on bentonite, fibers, and interaction between fibers bentonite. influence mainly r...

Stone columns are being used to reduce soft soil settlement and increase load-carrying capacity. Since there is inadequate lateral support from the local native soil, undergoes excessive under vertical loading. This issue effectively resolved by suitably encasing stone column material geosynthetic with significant axial stiffness, which provides required additional confinement reported in liter...

Over the last fifteen years increased research interest has been observed on the dynamic response and stability issues of landfills. Nevertheless, there are still important aspects that have not been yet fully resolved. Geosynthetic liners, constructed to isolate waste material from the environment, are undoubtedly one of the most important issues related to seismic design of landfills, since a...
