Evaluation of the Most Appropriate Implementation of Dolaei Tunnel Support System A Fuzzy Logic

The aim of this research is study the most appropriate implementation of tunnel support system among the common support systems based on Fuzzy logic approach. This paper is according to Fuzzy Multiple Criteria Decision making and in line with FAHP (Fuzzy Analytic Hierarchy Process). It concerns Dolaei tunnel of Touyserkan located in Hamedan province, Iran. To do so, this makes use of FAHP including six major effective criteria for choosing the most suitable implementation of tunnel support system as well as five different alternatives utilizing Steel support and with shotcrete , bolt cable, Lattice girder and shotcrete, prefabricated concrete segments and rock bolt or reinforced shotcretes. For calculative purposes, this paper utilize an application programmed in Visual Basic. Having done necessary investigations and assessment results indicate that implementation of rock bolt and reinforced shotcrete is more appropriate than other methods of tunnel support systems.
