|Abstract:||Compacted Clay Liners (CCLs) made-up of soil of low permeability characteristics are generally prone to damage when subjected to non-uniform settlements. Non-uniform settlements lead to bending and are critical for the behaviour of clay liners. As a result, the clay liner could loose its integrity and sealing efficiency. In this paper, relevance of centrifuge modeling technique for studying affect of non-uniform settlements on the integrity of the CCL of a liner system is presented. The centrifuge tests were carried out at 50g by simulating non-uniform settlements of a landfill using a trap-door arrangement. In addition the possibility of using a geogrid layer within the CCL to retain the integrity is brought out.|
