摘要：To ensure that the tunnel elements can be immersed and landed safely, an experimental study with scale model tests was performed to investigate the dynamic responses of the immersing tunnel element under random waves. The experimental measurements revealed quantitatively the dynamic behavior of the tunnel element and hoist ropes under different wave climates and negative buoyancy. From the results, we observed uncontrolled motions of the element and slack in the hoist ropes during the stage of freeboard elimination. Thus, an important conclusion is that the freeboard elimination scenario should be checked against cable breakages and the stability of the tunnel element in the design stage, which has not been highlighted in the past literature.
