Liquefaction potential assessment based on laboratory test

Abstract

The physical properties of sand soil which give effect to the resistance of liquefaction include grain size and density. Those physical properties of sand soil associated to liquefaction resistance have been studied in laboratory. Based on that study, the method to assess the liquefaction potential then is proposed. In laboratory tests, the vibration source is given by using the shaking table. During the tests, the acceleration and settlement are recorded. It then concluded that there is a relationship between density and gain size particles associated with liquefaction resistance for certain acceleration of vibration. The cone penetration and relative density relationship has been developed based on experiments in laboratory. Based on the results of those laboratory tests, the liquefaction potential of a certain site then assessed. It is found that the relative density and mean gain size relationship can be used to assess liquefaction potential in sand deposits.
