After the occurrence of liquefaction due to earthquake, the settlement of soil layers damage to structures located on the ground or the underground. In the last two decades, different experimental methods were used to determine the rate of volumetric strain (settlement) and maximum shear strain based on field and laboratory test data. The main purpose of the present study is the evaluation of the rate of settlement after the occurrence of liquefaction in soils and study relationship between liquefaction potential index (LPI) and settlement. The results of the standard resistance penetration test along Tabriz Metro Line 2 used to estimate the liquefaction potential of soil layers in 54 boreholes. Then, the value of settlement in soil layers due to liquefaction in both dry and saturated soil layers were evaluated. In continue, LPI was calculated. The results of this study showed that the rate of settlement in saturated soil layers was remarkably higher than the layers above the underground water level and with an increase in the density of the soil layers, the rate of settlement and soil volumetric strain decreased. Also, there is a good adoption between LPI and settlement values in soil layers.
