| 1. |
In certain cases of constructing dams salt-containing soils serve as their foundation.
|
| 2. |
Under these conditions reliable operation of the structures can be provided only by developing special engineering measures to control dissolution.
|
| 3. |
All existing methods of protecting saliferous foundation soils of hydraulic structures from dissolution can be divided into passive, active, and combined.
|
| 4. |
The combined methods should be considered the most effective for preventing removal of salts from foundation soils by the seepage flow.
|
| 5. |
Large-scale field investigations of the work of the combined method of protecting saliferous foundation soils of the planned Lower Kafirnigan hydro development showed its high effectiveness even in the case of complex engineering-geological conditions at the construction site.
|
| 6. |
Individual elements of the set of dissolution protective measures investigated under field conditions can be used in hydrotechnical and hydropower construction practice.
