... damage zone (EDZ) with higher hydraulic conductivity than the undisturbed rock mass. This paper studies the groundwater pressure in the rock mass surrounding the Gevingåsen tunnel, a drill-and-blast railway tunnel in Trøndelag, Norway, lined in the walls and crown with an undrained lining structure...

... as a function of their hydraulic conductivity, mechanical properties and geometry is necessary for evaluation of the stability of the fractured rock mass. The stability and tightness of a hydrocarbon storage cavern in a fractured rock mass have been modelled using DISROC ® finite element code developed...

..., Young's modulus and cohesion. However, the addition leads to a decrease in the optimum moisture content, angle of internal friction and the hydraulic conductivity of sand mixture. Optimum performance of the bentonite-sand mixture was observed when the mixture contained equal amounts of sand and bentonite...

... Abstract Field measurement of rock mass permeability is essential that numerous factors influence its directional magnitude. Lugeon test is a popularly conducted field instrument in order to measure hydraulic conductivity of a rock mass. Discontinuity orientation, spacing and discontinuity...

... Abstract The advantage of using centrifugal acceleration as a fluid driving force is that it acts as a body force in a way that is similar to that of gravity. To compare the saturated hydraulic conductivity of impermeable rocks, constant head tests under centrifugal acceleration and gravity...

... Abstract: Grouting, which involves injection of grout material, is commonly used to decrease the hydraulic conductivity of the fractured rock masses and control the groundwater inflow. Since underground facilities were constructed in various geologi-cal conditions, different types of grout...
