The buoy type suspension tunnel has stronger adaptability to different water depths and spans, but has higher sensitivity to wave currents because the buoy is built on the surface of water flow. And since the suspension tunnel is usually constructed in a deep sea area, the tidal range is often large. When the sea level is higher than the still water level, the buoy has the tendency of floating upwards, and additional upward pulling force is generated on the main body structure of the tunnel; when the sea level is lower than the still water level, the buoy has a tendency to sink, and additional downward thrust is generated on the tunnel main body structure. This cyclic reciprocating tidal load affects the stability of the tunnel body structure, which can cause fatigue damage to the structure.
