Increasing the bearing capacity of piles according to field experiments
In close connection with the issue under consideration, the question is about the degree of increase in the bearing capacity of the pile during time and determining its maximum resistance based on the results of early tests with static or dynamic loads.
Comparison of calculated precipitation in time with experimental data showed a satisfactory coincidence of the predictable speed sediment.
To confirm the laws discussed in this work associated with processes leaking in clay soils around the piles after their immersion, field and laboratory experiments are of great importance. Starting them, the authors were fully aware of the complexity and variety of conditions in which piles work in clay soils. The piles themselves can be made of various materials, have different shapes and sizes, plunge into the ground in various ways. In turn, clay soils, in which piles are immersed, are no less diverse in their composition, structure, texture, complexity, state and properties, therefore the main goal of the set experiments was to study the kinetics of increasing the bearing capacity of a single pile with a point immersed in claye soil with clogging.
Field experiments were conducted on the territories of the geological and geodetic base of the Leningrad Institute of Railway Engineers (Liizht) in the Luzhsky district of the Leningrad Region. The experimental plot was located on the outskirts of the watershed between the rivers Oredezhe, foot and black water and black and was a flat area obliged by its relief to the movement of the glacier.
On Devon’s deposits are the thickness of the morn (boulder) loam and less often clays with a small amount of rough -luminous, in particular boulder, material. The loams are dense, heterogeneous, mostly tight, brown. Their power is approximately 3 m. Moraine deposits are overlapped with slightly podzolic soils with a layer of up to 1 m.
