TUNNELING MACHINE SELECTION MODEL BASED ON GEOLOGIC PARAMETERS USING AHP METHOD CASE STUDY: NOSOUD WATER TUNNEL (2014)
According to the features of tunnel drilling machine that are not easily removable after start to work, and geological parameters that makes these devices functions be different in different contexts. On the other hand, causes to detect the excavation team and their weigh influencing on TBM devices choice. For this purpose this article after identifying these factors using AHP method classified them and studied them for case study of Nosoud water tunnel. This study can be classified in terms of functional results and in terms of executive approaches it can be classified in analytical category. The results showed that among the two main factors: geological and geotechnical hazards, the greatest weight is related to distance between joints sub factor in geological factor. Also, among single-pass drilling, open and telescopic machines the recent car considering all factors considered as the best drilling machine.
