Geotechnical study and analysis of the stability of pit walls

Abstract. One of the main problems and challenges in the field of geotechnical is excavation and conservation of existing buildings in the vicinity of them. In the case of non-compliance with the appropriate procedures in order to protect deep and the slopes are being built, there is the possibility of causing irreparable damage. Therefore, it is necessary to drill before using the support system side, a secure and stable environment be created to protect the pit walls. There are many methods for stabilizing ring. Such as by nailing, micro-piles, bracing and anchors, retaining structures truss and so on. The purpose of this paper is to examine the range of geotechnical and geological project is a monument in the city of Ardabil. According to the geotechnical characteristics of the site excavation pit wall stability analysis using the software limit equilibrium Geostudio / Slope.w and finite element software Plaxis 2.D. Discussion stability of deep excavation and the use of armed guards to protect the walls of the hollow structures with increasing levels of underground parking have always been important. The overall stability is seen in deformation and deformation of both side walls and the deepening meeting. As well as the stability of the structure in the vicinity of the ring depends on how the pla
