Türkiye'nin En Uzun Sulama Tüneli Suruç Tünelinde Geoteknik ve Tahkimat Tasarimlari

Abstract

This research concerns with geotechnical and support designs along the Suruç tunnel, which will be used for irrigation of the Suruç Plain. The tunnel has a diameter of 7.9 m. It will be the Turkey's 1st and the World's 5th longest irrigation tunnel (17.2 km). The tunnel runs through limestone and marly formations. Field studies include rock mass characterization (by using RMR, Q and GS I systems), discontinuity surveying, drilling, permeability tests and sampling. Support requirements were determined by using the rock mass classification systems, and evaluated by the convergence-confinement method and Plaxis 8.2 software. The minimum deformations (0.90 mm) occured in precast lining.
