Slope stability analysis using combination of pile and anchorage case study Kerman city

In recent years, with the increase of excavations in urban areas such as public transport systems (subway, underpass, etc.), the construction of huge structures, parking lots, as well as increased depth of operation in open pits, the issue of maintaining the stability of the slope is of particular importance. One of the most important issues in the stability of the slopes is the choice of a technically, executive and economically method. One of the solutions proposed for such problems is the method of Slope stability using a combination of piles and anchorage. In this method, firstly, the piles in the drill are executed in the excavated hole, and afterwards, the excavation and the anchorage of the stage are applied to the stage. Therefore, using thegeotechnical data of Kerman and using the finite difference software FLAC3D, a stabilization system was performed using a combination of piles and anchorage on the slope. The results of this study showed that in Kerman, slopes with less than 50 degree slopes will not be stable andwill not require maintenance. Also, slopes with a gradient of more than 70 degrees were unstable. For the vertical wall, the combined design preservation system plan includes 18 angles with 10 degree mounting angle, 4 piles and 10 cm shotcrete, which was both economically and optimally optimized for the safety coefficient of safety, and provided the desired slope stability
