Assessment of static and dynamic stresses horse-shoe tunnel with connecting gallery using finite element method: (as a case study) [PDF]
This paper illustrates the use of MIDAS GTS NX to investigate the tunnel’s simulation in order to highlight the effect of static and dynamic load on the behaviour of tunnel to compare this response expressed in terms of displacement and stresses ...

Influence of the Tunnel Shape on Shotcrete Lining Stresses [PDF]
Tunnel excavation is frequently carried out in rock masses by the drill and blast method and the final shape of the tunnel boundary can be irregular due to overbreaks.

Selecting a variant to allocate a plant producing shotcrete while implementing method of “wet” pneumatic concrete placing in Orlovskaia mine [PDF]
Purpose. Mining and geological conditions are complicated due to the decreased level of mining within deposits of West Kazakhstan. It results in significant increase in the amount of metal framed support which cannot always provide safety of mine ...
