Due to the widespread problem of excavation in urban and non-urban constructions, the importance of stabilization of excavations and walls is felt more. One of the methods used in this matter is the use of steel sheet pile walls. When using steel sheet pile wall, the soil in and around the site may be of weak soil type for backfill, so it is necessary to strengthen this soil by using different methods. In this research, using the available information about the characteristics of the mixture of sandy soil and tire chips with volume ratios of 15 and 30%, the behavior of the sheet pile wall with different heights, under the effects of increasing the depth of the reinforced layer in the backfill, with The use of PLAXIS finite element software is investigated. The results show that the use of a mixture of sand and tire chips in the backfill part of the wall instead of full sand backfill leads to a reduction in the lateral displacement and the bending moment of the sheet pile. Also, the anchor force decreases. In this case, the settlement, increases to a small amount. Also, by increasing the depth of the reinforced layer, so that the entire backfill is reinforced with tire chips, the lateral displacement and bending moment of the sheet pile is reduced.
