چکیده مقاله
With respect to the frictional performance of the 3D panels studied in this research, the tunnel wall friction plays an important role in distribution of internal forces and consequently optimum design of tunnel support system, hence, the main objective in this study is achieving the appropriate range of the wall friction and based on this range, determining the most accommodating soil type In this article the tunnel cross section has been assumed as a reinforced concrete, and also it is assumed that the soil cohesion has no effect on the analysis In the both static and dynamic condition, for different values oftangential spring stiffnesses, analysis of the tunnel structure,using SAP 2000 software, was carried out and by means of interaction diagram, optimal range of wall friction ascertained As a consequence this study, in the static analysis more wall friction prefers whereas having less wall friction, in the dynamic analysis, is better
