Papers Discussion on Construction Norms

Conclusions

  1. 1.

    The construction plans for hydraulic tunnels and underground structures for hydroelectric stations require designing on the basis of scientific investigations of the physicomechanical characteristics of rocks, carried out during excavation.

     
  2. 2.

    For hydraulic tunnels and underground structures of all classes the calculation of rock pressure must be carried out on the basis of scientific investigations. However, when carrying out calculations in stages of the project development rock pressure can be calculated also by well-founded equations and analogies.

     
  3. 3.

    When determining the wall pressure and elastic characteristics of the rock it is necessary widely to introduce contemporary leading geophysical methods of surveying, including seismic surveying.

     
  4. 4.

    The value of the rock pressure for spalling rocks depends on the fracturing and the dip of the strata and not on the coefficient of stability.

     
  5. 5.

    It is necessary to refine the coefficient a for significantly fractured rocks.
