Abstract :

This study includes the determination of the liquefaction potential of Manisa (Saruhanlı) region effect of relative density on liquefaction using seismic waves in field and dynamic triaxial test in laboratory. It was predicated that the Gediz Graben Fault Zone was a length of 150 km and to affect the region and approximately passed through in a distance of 33 km in the south of Saruhanlı District. In a probable earthquake effect, in case Gediz Graben was cracked 1/3 of the total length and it would produce as MW=7,1 and a max=0.28 g and the liquefaction analysis was performed and liquefaction map was prepared according to this approach. The samples were obtained from site according to the liquefaction hazard map and reconstituted basing on relative densities bounding to their own location relative densities in laboratory. They were subjected to stress-controlled cyclic loads sinusoidally according to the cyclic stress ratios obtained from site conditions conslidated to the stress which was exposed to the influence of geological overburden in-situ field stress. The tests were performed at the frequency of 0,5 Hz. In the end, under these conditions this sample was not liquefied and then in case, relative density rate reduced % 50 and redone the experiment, same sanple was liquefied.
