The repeated occurrence of liquefaction can be added in sand deposits under successive shaking events is of much practical interest due to historic successive earthquake events. Severe damages incurred during the successive/repeated shaking events around the world. A proper ground improvement system needs to be adopted to mitigate liquefaction and structural damages, especially during the application of repeated shaking events. In the present study, techniques such as prefabricated vertical drains (Drainage mechanism) and Sand compaction piles (Densification mechanism) were used to assess and compared liquefaction and reliquefaction phenomenon during repeated shaking events. A Perspex tank of dimension 1.4 × 1 × 1 m was used and mounted over a 1-g uni-axial shaking table. Poorly graded Solani river sand was used for sample preparation. A saturated sand-bed of 600 mm thickness having 40% relative density was prepared for the study. Repeated incremental shaking events were applied to the ground of intensity varying from 0.1–0.4 g with 5 Hz frequency. A scaled down model shallow foundation placed at the center of the tank for estimating foundation settlement during repeated loading. Relative density variations during installation of improvement techniques and the performance after each shaking event were estimated. The performance of the installed improvement system was evaluated in terms of maximum pore pressure ratio and the settlement of the foundation model. The observed experimental test results indicate that the efficiency of treatment techniques is significant in mitigating the repeated liquefaction during successive shaking events.
