Problems of improving the quality of hydraulic tunnel linings and preventing their damage during operation

  • Published:
Hydrotechnical Construction Aims and scope

Conclusions

  1. 1.

    The majority of linings of hydraulic tunnels during their operation receive various damages — considerable leaks of water from the tunnels are observed, the working and technological joints open and large cracks form in the linings, the surface roughness increases, and the linings are destroyed in individual sections of the tunnel. As a result the capacity of the hydrostation decreases, and in individual cases emergency situations related to loss of stability of the tunnels and sliding of the mountain slopes are created.

  2. 2.

    The recommendations given in the present article permit improving the quality of linings and, to a considerable extent, preventing their damage during operation of hydraulic tunnels.
