Abstract :
Liquefaction is a phenomenon in which the saturated soil loses its strength and hardness due to the intense stress it behaves like a liquid. This phenomenon mostly occurs in sandy saturated soils with low densities, non- plastic silt and it occurs less in gravel and clay. The soil texture, high level of groundwater in different parts of the city, the seismic conditions in the soils of the study area and the importance of the project in this case study, show the compulsion of studying the liquefaction phenomenon. In this manuscript, to evaluate the liquefaction capability of sandy soils, the simplified Seed and Idriss design and the results of the standard penetration test (SPT) have been used and for the silty soils, the Japanese method and for fine-grained cohesive soils, Wang theory has been used to evaluate the liquefaction potential. Finally, the liquefaction potential of the study area evaluated medium to low due to the SPT numbers, soil texture and the PI index of the region soils.
