A SIMPLE SHAKING TABLE TEST TO MEASURE LIQUEFACTION POTENTIAL OF PRAMBANAN AREA, YOGYAKARTA, INDONESIA

This paper presents the experimental study of liquefaction potential for sandy soil in Prambanan Area, Yogyakarta, Indonesia, which underwent due to Mw 6.3 Jogja Earthquake on May 27, 2006. Shaking table tests considering variation acceleration and shaking duration were performed investigate sand. The time stages including start liquefaction, pore pressure dissipation, observed. percentage increase, excess water ratio required generate effect applied cyclic stress ratio, also presented. results showed that sand could undergo under dynamic load. load significantly influenced increase ratio. exhibited larger longer means potential. In general, result bring recommendation countermeasure Area.
