Abstract

The assessment of liquefaction potential is very important and is the main step in making a map of liquefaction hazard in a certain area. The assessment methods of liquefaction potential have been proposed by researchers since last eight decades. Each method is based on the purposes and completeness of the data obtained by the developer. In this study, these methods then were modified to propose the new method that is easier and technically cheaper. Furthermore, the method will be applied in making liquefaction
hazard maps. The method as a result of this study is a new procedure that is more practical to be applied. This method is associated with soil parameters that are commonly and easy obtained in general soil investigation. The soil parameters used to assess the potential of liquefaction in this procedure are the density and mean size of soil particles. Soil density and particle mean size needed for analysis of liquefaction potential can be obtained from laboratory tests or the correlation results from the value of field tests, namely the standard penetration test or cone penetration test. This new procedure is expected to be more applicable and reliable in
making liquefaction hazard maps.
