Control of operational and technical aspects of grouting works in tunnelling and heavy construction
Abstract: Grouting works have become a key essential part of temporary and permanent works in the fields of tunnelling and complex demanding construction projects, mainly in the forefront of construction to sufficiently prepare weak ground to meet the prerequisites for construction. Grouting measures are hereby often carried out as a specific measure with the emphasis to increase the bearing capacity...

Unexpected performance and cost factors for hard rock TBM. Analyses of specific cases with the thrust-penetration...
Abstract: In the common view of tunneling experience, discontinuities are considered with downscaling effects on the mechanical properties of rock mass. The effect of discontinuities in mechanized hard rock excavation is of ambivalent nature. The presence of favorable number and orientation of joints leads in general to a reduced effort for TBM excavation and higher advance rates; where else the same...
