摘要： A device for simulating suction penetration of suction caisson based on centrifuge model test includes a model box, a suction caisson model in the model box and containing a suction caisson and a connecting rod, a penetration device disposed above the model box and movably connected to the connecting rod, a vacuum system connected to the suction caisson, a lower part of the suction caisson is provided with soil, and an upper part of the soil is provided with a water body. The penetration device includes a guide rail and a drive lever. The drive lever penetrates through the model box and then is connected to an electromagnetic adsorption device, a bottom end of which includes a guide housing, and the connecting rod is inserted into the guide housing. The device can dynamically correct displacement deviation in a suction penetration process, thereby being continuously tested in a centrifugal state.

摘要： A model test device for simulating environmental load and scouring effect on a suction caisson includes a laminar shear box. Multiple scouring pit simulation mechanisms are arranged around the suction caisson inside the laminar shear box, each scouring pit simulation mechanism includes a bracket disposed in the laminar shear box, the bracket is equipped with a telescopic arm connected to a cutting plate, and the cutting plate is curved fan-shaped. When the cutting plates move to positions where they are in contact with an outer wall of the suction caisson, the cutting plates are mutually connected to form a ring surrounding the suction caisson. An inner edge of the ring forms a complete circle attached to the outer wall of the suction caisson, an outer edge of the ring is higher than its inner edge, and the outer edge is located above the saturated soft clay in the water body.
