Abstract

Desiccation cracking is a major undesirable problem to many geo-engineering applications, particularly in compacted clay liners, which causes the significant change to the strength, stability, and permeability of soil. This study is used to investigate the effect and causes of desiccation cracking in the clay liners during wetting and drying conditions. Researchers measured the use of surface moisture barrier above the clay liner, but studies shows that repeated cycles with temperature changes in seasons results in significant desiccation of the clay layer and associated cracking. Recently most of the researchers have been focused on reinforcing the fibre with clay soil will reduce the crack formation. Mainly polypropylene fibres play a major role. The crack formation was measured using crack intensity factor (CIF). It was observed CIF of the soil without fibre will significantly higher than the soil with fibre. Use of fibres to reduce the desiccation cracking in compacted clay has caught the attention of geotechnical engineers. An effort consequently made to understand the formation of cracks in clay liner materials and to manage the desiccation cracks by use of fibres.
