METHOD OF COMPACTION OF FOUNDATIONS  AND STRUCTURES VIDRATORI FOR  DIP TONGUE  IN HYDROPOWER CONSTRUCTION

Vibrator and developed on the basis of it the Russian method of the bases vibratory compaction by means of longitudinal vibration with spatial seal in the form of “vibroelochki” is widely used throughout the world to dive tongue and vibro sandy soils bases such as both saturated or slightly wet, and their combinations. The paper presents the results of a theoretical study on the developed simulation model and field tests of the method of deep vibro grounds showing its shortcomings. These disadvantages have been most clearly manifested when thick layer of sandy grounds (9m and more) was compacted. In this paper we show that a certain vibratory disadvantages can be eliminated or significantly reduced by the use of vibratory compactors with the placement of the radial elements at a given height in the bottom of the stem seal. This improves the vibratory specifications when working with reliable and economical vibrator.
