Experimental seismological measurement in railway tunnel Olbramovice
Stolárik, Martin
The paper describes another experimental seismological measurement in shallow tunnel, located at Fourth railway corridor. New Austrian Tunneling Method was used to construct the tunel using blasting operations on core.
Numerical modelling of dynamic response of the vibrated pile
Petřík, T. ; Hrubešová, E. ; Stolárik, Martin
In this work, we deal with the problem of analyzing the dynamic effects caused by the realization of the vibrated pile (in the industrial zone Poříčany). Software named Plaxis 2D is used for numerical modeling. Experimental measurements carried out by Institute of Geonics AS CR are used for model creation, especially for the determination of seismic loading. Obtained results document impact of vibrated pile realization on the geological mediums.
Schemes of seismic experimental measurements in the railroad tunnel Mosty u Jablunkova
Stolárik, Martin
It comes to general reconstruction of obsolete main railroad tracks and development of railway corridors in Czech Republic. In relation to this, new railroad tunnels are built, or present ones are reconstructed. Reconstruction of old tunnel represents tunneling of new underground space. The cross section of singletrack tunnel is often enlarged to double-tracked one. New tunnel constructions are realized using New Austrian Tunneling Method (NATM) when blasting operations are one of driving technologies. Typical example of this reconstructed tunnel is tunnel in the mountain pass Jablunkov. Two single-track railroad old tunnels are situated in this location. The older tunnel (1871) operated at the present time as a provisional and the junger one (1917) reconstructed. Both of them are near one another. Experimental seismological measurement was realized in the reconstructed tunnel on the tunnel floor.
