Rock mass classification systems are valuable tools for estimating design parameters of rock
engineering projects. In some cases, due to the lack of enough geological data, it may not …

To deal with a water inrush issue that occurs in deep mines in China with more than one
aquifer below the floor, the “down three zone” analysis method was modified to establish a …

Rock mass classification systems play a crucial role in estimating the design parameters of
rock engineering projects. However, the availability of geological data may sometimes be …

This paper presents an improved risk assessment model to evaluate the risk of water inrush
in karst tunnels based on matter element theory and ideal point method. The 4 first-grade …

The Gerede is the longest and most problematic water transmission tunnel in Turkey, at 31.6
km long with an overburden of 600 m. The tunnel will transmit water from the Ulusu river to …

Water rich tunnels are often subject to lining seepage and water leakage. The water
pressure behind lining is the main factor that causes the tunnel diseases. To calculate the …

The complex interaction between the cutters and rocks in the tunnel face makes it difficult to
predict the cutter wear, exactly. Therefore, many researchers have tried to study this process …

Water inflow caused by tunneling can have severe impacts on the springs' discharge rate. If
these impacts have not been predicted beforehand, technical, economic, and environmental …

This paper aims to assess the influence of in situ stresses and geometry of the fracture
surface on the behaviour of fluid flow through rock fractures. In this regard, fluid flow tests …

Groundwater inflow into rock tunnels depends on the geologic and hydrological conditions.
There is no complete standard method for estimating the exact volumes and locations of …
