Conclusions
-
1.
Improvement of the layouts and designs of underground hydraulic structures by combining the functions of tunnels, using designs involving the surrounding rock in work, and also the use of precast structural elements is an important reserve of scientific and technological progress in underground hydrotechnical construction.
-
2.
It seems expedient to use the described designs in objects that are being designed and to organize and conduct investigations to substantiate these designs for particular objects, including future ones.
-
3.
Since the majority of progressive designs are possible only if a smooth contour of the workings is provided and overbreak of rock and overplacement of concrete bring harm, it is necessary without delay to develop and introduce an effective technology of smooth blasting in Soviet underground hydrotechnical construction for the most characteristic engineerhing-geological conditions.
