The influence of various parameters of physical and mechanical properties on susceptibility to liquefaction of sandy soils

Abstract On September 30, 2009, there was liquefaction in the sandy soils around coast of Padang city, which triggered by an earthquake measuring 7.6 SR. Liquefaction causes land subsidence and lateral displacement many buildings Padang. The level vulnerability city is moderate zone based on qualitative methods; contrary, quantitative methods obtained a very high to liquefaction. Based this, conducting geotechnical investigations field laboratory tests are needed determine potential. This study aims potential for using testing physical properties mechanical laboratory. standard Indonesian National Standard (SNI), soil sampling carried out seventeen areas. results properties, i.e., relative density (Dr), particle size soil, internal friction angle, showed that along poorly graded sand (SP). dominated fine with loose consistency, has
