Given the increasing urbanization and the lack of land in urban areas Long lifting and deep excavation are of special importance Especially in recent years . now a daysThe issue of deep excavation In urban spaces, much attention has been paid These excavations are very suitable for the construction of underground structures . But it can be dangerous for lateral structures and cause displacement As well as the problem of entering the neighbor's privacy . This research is intended to optimize the balance of the strut levels in a urban deep excavation with a two-level strut system In order to avoid additional costs The use of heavier profiles and the placement of struts . For this purpose software Plaxis 2D software Foundation models are made and after analyzing In the alignment, the lowest amount of horizontal displacement is crowned an‎d the highest percentage of Strut load In order to bear the adjoining lateral pressure that possible from the soil around that . In this study, it has been shown that the optimal level used to locate the struts In a hollow with a height of 8, 10 and 12 meters With the default soil parameters used in the research process (0.35 and 0.75) is the height of the hole
