Testing system simulating ultimate dynamic bearing capacity of cyclic load lower plate anchor
The invention provides a testing system simulating the ultimate dynamic bearing capacity of a cyclic load lower plate anchor. The testing system comprises a plate anchor model, a cross-shaped supporting frame, a cyclic loading device and a measuring device, wherein the cross-shaped supporting frame is used for limiting an anchor shank of the plate anchor model to move perpendicular to the seabed surface. The cyclic loading device is used for exerting cyclic loads on the anchor shank and comprises a transmission device, a cyclic load and displacement load converting device and a displacement correcting device, the transmission device is used for converting constant-speed rotation input by a motor into sine simulating reciprocating rotation, the cyclic load and displacement load converting device is used for converting the reciprocating rotation into superposition of appointed constant loads and sine simulating loads, and the displacement correcting device is used for adjusting the length of a rope according to the displacement of the plate anchor model so that it can be avoided that the amplitude of the cyclic loads is attenuated due to the displacement accumulation of the plate anchor model in multiple periods. The amplitude of the cyclic loads can be effectively controlled, pore water pressure of a soil body around the plate anchor in the circular drawing process is obtained, the destroying process of the plate anchor and the soil body around the plate anchor is directly observed, and the ultimate dynamic bearing capacity of the cyclic load lower plate anchor is reasonably evaluated.
