STATIC AND DYNAMIC TESTS OF METAL PILE-SHELLS OF A SEA PIER MARINE TERMINAL

The behavior of the piles in the engineering and geological conditions of the construction water area of a new two-way pier of the berth on the territory of the sea trade port of Chornomorsk as a part of the expansion of production capacities for transshipment of grain, food products, processing of oil and grain crops was studied. During the construction, it is envisaged to use shell piles made of metal pipes 35.0...42.7 m long with the outer diameters 1020, 1220 and 1440 mm. The layers include Neogene sediments of the upper Miocene subdivision of the Sarmatian and Meotic horizons, which are represented by clayey soils from plastic to hard consistency with the lenses of silty sands saturated with the water and the interlayers of limestone. The piles cut through the sporadic layering of loams and clays, and their bottom ends are stopped in clay and dusty sands. A comprehensive approach to conducting the control tests of the piles was developed, which included conducting the tests in two stages. At the first stage, a group of four piles with the diameters 1020 and 1220 mm were tested under both static and dynamic loads at the construction site on the first supporting structures. The
