Kytovskyi S. Ensuring the bearing capacity massifs inwashed soils with weak
underlying layers. - The manuscript.
The current state of building activity was examined on alluvial areas with weak
underlying layers. And also we examined the ways of ensuring the bearing capacityof the soil. The most appropriate and effective way was fawn foundation of bored
piles. The effect of hydrodynamic pressures of squeeze pore water was determined on
the soil skeleton. This process was studied in manufacture of augered piles with
vibrocompaction. We established that the hydrodynamic pressure wet and saturated
alluvial sand can cause hydrodynamic prudent array and wring pore water. We
identified dimension of hydrodynamic pressures that squeezed pore water and create
a hydraulic gradient array of water-saturated soil.
For the first time simulated the compaction process wet and saturated soils by
extraction of the pore water in the concrete mix vibrocompacted in the manufacture
of bored piles. It is established that the vibration wave creates forced (push-UPS)
pore water movement, speeds up the filtration process and interacting with the
particles of soil compacts it. Stacked differential equation of soil compaction due to
the effective compressive stresses pore water vibrational forces, and without taking
into account linear creep of the soil skeleton.
For the first proposed method for determining stress components at any point
of the soil body from the action of vertical loads in the bottom end of the pile at great
depths in vibrocompacted. Stacked and solved the differential equations of stress
components at any point on the great depth of soil from the vertical load, using the
biharmonic stress function satisfying the boundary conditions harmonic equations.
The use of biharmonic functions of strains, the so-called functions of the common
Era, have allowed us to construct the solution in a General form and give to the
differential equations of versatility.
