Abstract

The occurrence of an earthquake or the other periodic loads in areas where the underground water level is high causes the reduced resistance of sandy soil. This decrease in the resistance of sandy soil is called liquefaction and if there are buildings and facilities, it causes serious damage to them. In this research, the potential of liquefaction of sand in Durood city during the earthquake of 2015 is investigated. For this purpose, at first, sand samples with a history of liquefaction were taken from the depths of 1.2-8.7 and 2.3-5.5 meters from the liquefied residential area and were taken to the laboratory to perform the required tests. The results show that the addition of 2% cement causes an increase in the resistance parameters of sand, so that the friction angle increases from 24 degrees to 29 degrees and the cohesion also increases from 1 kPa to 13 kPa.
