ESTIMATING GROUND SETTLEMENT POST-LIQUEFACTION USING CPT

The Universitas Muhammadiyah Yogyakarta (UMY) campus is constructed on 28 hectare which mostly rested on a sand deposit layer and the ground water table was shallow relatively. During earthquake on May 27, 2006, a magnitude 6.3 struck the provinces of Yogyakarta resulted in number of seismic damages...
