Abstract
Loose saturated cohesionless soils may undergo liquefaction due to strong ground motions. Such liquefaction causes significant damage to the structure resting on such soil. The extent of damage primarily depends upon soil properties, intensity of earthquake and type of structure. Various analytical models have been developed to estimate the likelihood of liquefaction of particular site based on field performance. However, if it is possible to identify the sites which are likely to liquefy due to specific intensity of earthquake it will help implementing the reduction in the damage which it would otherwise cause. One such analytical model has been developed by one of the authors of this paper and has been found to satisfactorily demarcate ‘Yes’ and ‘No’ zones of liquefaction for number of earthquakes. However, earlier research shows that laboratory tests could also be conducted to study the liquefaction behavior of soil under specific condition. The present study mainly deals with an attempt made in conducting Shake Table Test in laboratory by simulating earthquake conditions on site. The results obtained from the trial tests have been compared with the actual field cases and also with laboratory tests conducted for such soil by other researchers. It is observed that the criterion of the occurrence of liquefaction in the laboratory model is in close agreement with actual field data. Shake table test is found to be more effective in simulating the strong ground motion during earthquake.
