abstracts | The paper focuses on two pressure tunnels in the design of “Kąty-Myscowa” water reservoir.
One of them serves as a discharge conduit, whereas the other plays an energetic role. Their
depths range between 0 and 75 metres and their diameters equal 5 m. Tunnels are located
in the rock mass of Carpathian flysch which is anisotropic and heterogeneous, composed of
layers of sandstone and clay shales and intersected with interbedding fissures and numerous
joints. The paper is divided in two parts. The first part focuses on methods of excavating and
supporting, as well as injecting and sealing (i.e. waterproofing) the tunnel. In the second part,
a numerical analysis using the FLAC2D code based on the finite difference method was carried
for calculating displacements and internal forces in the preliminary support and in permanent
lining. Results of the analysis allow for the assessment of conditions in the tunnel during its
excavation and exploitation stages. |
