... at the tip of the penetration cone that occurs during dynamic penetration (Sawada, 2004). However, it takes time to analyze the measurement results, and the confirmation test is conducted after the curing period following ground improvement construction. Therefore, it is difficult to instantly reflect...

... by performing well-controlled experiments, where we use an inverted, hollow cone as an impactor. The cone is kept immersed throughout in a water bath, such that it encloses an air bubble of known and controlled volume. A high-sensitivity sensor measures pressures at the vertex of the cone. Using high-speed...

... ABSTRACT In the paper, the hydrodynamic problem of a cone entering the water through the free fall motion has been analyzed based on three dimensional (3D) velocity potential theory. The fluid is assumed to be inviscid and incompressible, the flow to be irroatational and the gravity effect has...

... at Tianjin University. The model of the jacket platform consisted of four legs with upward-downward ice-breaking cones and a 4×5 conductor array, and the ice pile-up process was achieved by towing the model jacket through the ice sheet under different speeds, directions and water levels. During the tests...

... Abstract The ice-induced structural vibration is basically controlled by the value and period of dynamic ice force. For the conical structure, the value of ice force on the upward cone is larger than downward cone and the ice force period is much more complex. Field measurements in the Bohai...
