Abstract

In this research, One method, based on the SPT test number, was used to evaluate liquefaction potential of the sand layers for river navigation at the Khorramshahr dam and shipping lock construction site. For fine-grained layers, another method  have been used. For level 1 and level 2 earthquakes (with return periods of 75 and 475 years), the limit to ensure against the risk of liquefaction is assumed to be 1.5 and 1.1. For each pile, the number of blows to penetrate each meter of their length is calculated. Normaly, the compression caused by striking the first series of piles has increased the number of blows required to penetrate the second series of piles. The ratio of the increase in the number of blows necessary to penetrate each pile of the second series relative to the first series has been calculated. The obtained increase rate is assumed to be equal to the increase of SPT number. Calculations to determine the safety factor against liquefaction have been done again with new SPT numbers. Application of the proposed method shows  reduction of the levels and depths of liquefaction caused by the density of layers due to penetration of the piles. In the example case (Mard dam and its ship), the relative increase of SPT number was nearly 20 percent. Therefore, the proposed method has reduced the liquefaction zones by 8%. In addition, in the areas that have been diagnosed as low liquefaction potential in the studies, but had a low confidence factor, a 9.5% increase in the confidence factor against liquefaction has also occurred. By increasing the SPT number, the proposed method can increase the accuracy of liquefaction calculations in the sites.
