Abstract

When the tunnel passes through the weak and different soil conditions or there is a shallow coverage on top of the tunnel, mass of soil or sand have to be made stable and the SUPPORTS must be designed and applied in a way to control the amount of SUBSIDENCE and CONVERGENCE which are the most significant factors in designing a tunnel since by changing the shape of the tunnel through drilling, the soil between the tunnel and the surface of the ground move. And the development of these movements to the surface of the ground will be accompanied with the SUBSIDENCE of the surface structures. Therefore in order to do necessary planning to create SUPPORTS considering the conditions of the location of doing the project, providing a decision making model is essential in choosing an appropriate option for tunnel SUPPORTS in planning phase and designing the tunnel project. The aim of this paper is to provide (offer) a useful design to specify and choose suitable options for Tehran subway tunnel SUPPORTS, 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 project by noticing a variety of criteria. Further more (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 sheet and segmental lining in the model. And the final goal is selecting the most suitable option aimed all the probable options for choosing subway tunnel SUPPORTS system and noticing effective and important criteria on which basis and by using multi-criteria decision making and new research methods during the operation, proper options are prioritize and ultimately the best ones are chosen. In TOPSIS method, alternative (E) is selected as the best alternative for support system.
