Levchenko V. Stress-strain state of the “drill and injection pile - foundation” system

The object are drill and injection pile are produced "Soletanzh" objective - evaluation of the stress strain state of the system "drill and injection pile - foundation" and to develop methods of calculating the bearing capacity of piles subject to additional compression of concrete in their manufacture, methods - theoretical and experimental, novelty - the first time in a Tray tests and field observations vtanovleno relationship between compression and bearing capacity of concrete drill and injection pile , while experimentally proved that the carrying capacity of piles increases with the increase of the pressure compression of concrete piles in its placement, a model system "drill and injection pile - foundation", which takes into account the effect of compression in the concrete placement drill and injection pile; results - a method for designing drill and injection pile considering the effect of compression concrete at their establishment; the field is building.
