Abstract

To ensure that the tunnel elements can be immersed and landed safely and accurately, 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 tunnel element under different wave climates and negative buoyancy. From the results, the dynamic response of the tunnel element was most severe 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 literatures.
