Introduction of geomorphological rock mass strength classification as a criterion for estimating the groundwater inflow into tunnels

Masoud Morsali

Volume 31, Issue 4 , December 2021, , Pages 69-78


  Prediction of groundwater inflow into tunnels during excavation is one of the most important problems of tunneling projects. There are many analytical and empirical methods to predict the amount of groundwater entering the tunnels, which are generally not highly accurate. Permeability and water head ...  Read More

The comparison of effective variables and methods in water inflow into hard rock tunnels (Case study: Karaj dam-Tehran water conveyance tunnel)

M. Morsali; M. Nakhaie; M. Rezaie; H. R. Naseri; J. Hassanpour

Volume 27, Issue 107 , June 2018, , Pages 113-122


  Tehran- Karaj water conveyance tunnel (part 1), 16 kilometers in length, in the Karaj formation was excavated in order to convey the water from the Amir-Kabir dam to the Tehran refinery plant. The hydrogeology studies of the Karaj tunnel were done to discover the affecting parameters on the groundwater ...  Read More

The role of tectonic structures and stratigraphy in predicting influx of water into the tunnel using remote sensing (Case Study: Nosoud water-transport tunnel, part 1-A)

M. Heydari; Sharafi M.

Volume 26, Issue 104 , September 2017, , Pages 69-80


  The use of remote sensing combined with field surveys can be used as an economic approach to detect the areas that are susceptible to the influx of water into tunnels. This study aims at investigating potential zones of groundwater influx in part 1-A of the Nosoud water-transport tunnel located in the ...  Read More
