ارزيابي پتانسيل روانگراييي در بخشي از نواحي جنوب شرقي تهران

Liquefaction Potential Evaluation Of South West Of Tehran

in this paper, an evaluation on liquefaction potential of a part of South-West of Tehran City, based on the simplified method proposed by Seed and Idriss (1985) is presented. PGA was estimated for the return period of 475 years, life time of 50 years and an earthquake with Magnitude of 7.5 in Richter scale. The studied area was divided into 1km*1km grids and geotechnical profile was evaluated for each grid. The Liquefaction Index determined for each grid using method proposed by iwasaki et. al (1982) and liquefaction hazard was evaluated based on this Index.
