Prevention of Crack Formed During the Electrokinetic Consolidation of Clayey Soil
摘要
Sustainable methods are being developed to improve problematic ground conditions, and electrokinetics has become a sustainable soil modification remediation technique. In this study, an attempt has been made to mitigate the formation of cracks during the electrokinetic consolidation of clayey soil. The clayey soil used in the study was obtained from Ramgarh village in the Samba district of Jammu and Kashmir. The experiments were conducted by varying the voltage gradient and adding a small quantity of lime to clayey soil. The efficacy of the electrokinetic consolidation process was evaluated in terms of pore water removal efficiency, surface settlement, and prevention of the crack. A total of seven experiments were conducted with different testing conditions. The study results reveal that when a voltage gradient of 1 V/cm is applied instead of 0.25 V/cm, the surface settlement rises by 50%. Further, when lime was added the power consumption was 3.67 times more than the test conducted without lime. However, the difference in power consumption was negligible at a voltage gradient of 0.50 V/cm with and without lime. Finally, adding 2.5% lime in clayey significantly lessens the surface cracks formed during electrokinetic consolidation.
