Earth dams constructed by the directional blasting method

  • Published:
Hydrotechnical Construction Aims and scope

Conclusions

  1. 1.

    The construction of earth dams by the directional blasting method is a powerful means of increasing labor productivity when performing earthworks and constructing water-retaining structures in mountain regions.

  2. 2.

    The available experience of hydrotechnical construction shows that such structures can be constructed and reliably operate at sites having the necessary topographic and geological-engineering conditions.

  3. 3.

    It is necessary to select a rational design of a dam being constructed by the directional blasting method in relation to the geological-engineering conditions of the site and purpose of the hydro development.

  4. 4.

    The realization of the construction of the cascade of Kambaraty Nos. 1 and 2 hydrostations will substantially increase the volume of knowledge in the given area and will permit proceeding to the wider use of the directional blasting method for constructing rock dams in mountain regions of the USSR.
