Abstract :

The aim of this paper is to offer a useful design to specify and choose suitable options for Tehran subway tunnelsupports, line 3, phase 4 as a good model for later stages use. This pattern is formed on the basis of technical,financial, administrating, social and political and mechanical and effective factors on the site of doing the projectby noticing a variety of criteria. Furthermore (on the other hand) subway tunnel supports include lattice girder,cement armed with armature using modular form work (frame work) system, fore poling, corrugated steel sheetand segmental lining in the model. And the final goal is selecting the most suitable option aimed all the probableoptions for choosing subway tunnel supports system and noticing effective and important criteria on which basisand by using multi-criteria decision making and new research methods during the operation, proper options areprioritize and ultimately the best ones are chosen. In TOPSIS method, alternative (E) is selected as the bestalternative for support system.
