Abstract: The Norwegian National Rail Administration is building a new railroad tunnel between Oslo and Ski. It is expected to generate between 9 500 and 18 700 tons of alum shales, CambroOrdovician black mudrocks, characterized by their high potential for generating acid rock drainage (ARD). This project illustrates an integrated management approach, from the characterization of the rock to the safe...
Abstract: The Himalayas is generally characterized by steep slopes, lofty hills, and complex geological and tectonic settings. Hence, detailed engineering geological investigations are warranted for planning new underground projects in the Himalayas. This paper describes a feasibility study performed for a planned road tunnel in Bhutan. The study included engineering geological mapping, rock mass...
