Slurry Shield Tunneling: New Methodology for Simplified Prediction of Increased Pore Pressures Resulting from Slurry Infiltration at the Tunnel Face Under Cyclic Excavation Processes

Autor: Britta Schoesser, Markus Thewes, Zdenek Zizka, Tom Schanz

Publikováno v: International Journal of Civil Engineering. 17:113-130

Within mechanized tunneling, slurry shields are used for excavations in soils with unstable tunnel face due to the possibility to support the tunnel face with pressurized slurry (bentonite suspension). Two key conditions have to be fulfilled to stabi

Publikováno v: Tunnelling and Underground Space Technology. 74:206-216

The wear of slurry shield TBM excavation tools is a challenging topic that has been discussed over many years, Due to the complexity of the tribological system that defines the tool wear, no sufficient approach to determine the wear in a specific tun

Investigations on the transient support pressure transfer at the tunnel face during slurry shield drive Part 2: Case B – Deep slurry penetration exceeds tool cutting depth

Autor: Markus Thewes, Zdenek Zizka, Britta Schoesser

Publikováno v: Tunnelling and Underground Space Technology. 118:104169

Stability of the tunnel face is a key design aspect for slurry shield tunnelling. Two requirements have to be fulfilled during excavation in order to achieve a stable tunnel face. The first requirement is a sufficient slurry pressure in the excavatio

Pathogens of the spruce bark beetles Ips typographus and Ips duplicatus

Autor: Jaroslav Holuša, Zdenek Zizka, Jaroslav Weiser

Publikováno v: Open Life Sciences, Vol 4, Iss 4, Pp 567-573 (2009)

Pathogens of two important bark beetles, Ips typographus and Ips duplicatus, both in outbreaks connected with infestation of spruces by the fungus Armillaria ostoyae, were compared at four localities in the eastern Czech Republic. Low infestations of
