Change in surface roughness of composite piles when pressing into the ground

The bearing capacity of piles on the ground is one main characteristics pile foundations, which responsible for its interaction with ground. This characteristic depends many factors: granulometric composition soil, moisture content, con-sistency, texture, as well type and properties material. One charac-teristics material surface roughness. In studies, dependence angle friction soil against value roughness was noted. At same time, all studies focused exclusively roughness, not paying attention to possibility variability in process driving into goal set framework this study. Using a standard single-plane cutter, passage composite at distance 0.5m simulated depth 10 m. Before after test, parameters were measured using Seitronic PSh8-1 SS device. results showed that fiberglass plate made basis polyester resin by pultrusion method decreased 44.4%.
