Disclosed in the present invention are a suspended tunnel shore connection system, a suspended tunnel, and a suspended tunnel construction method, the design method of the suspended tunnel being the respective application of axial tension along one or both ends of a tube body; the suspended tunnel shore connection system comprises a connector section positioned at the end part of the tube body, the connector section being capable of moving axially, and a tension apparatus for applying axial tension being connected onto the connector section; the suspended tunnel comprises the tube body having a hollow inner cavity, the tube body comprising a suspended section and a shore connection system positioned at both ends, and both connector sections being provided with a tension apparatus. The design method and structure of the suspended tunnel of the present invention, by means of applying axial tension to the tube body, can significantly increase the horizontal rigidity and vertical rigidity of the entire tube body, increasing the self-oscillation frequency of the entire tube body structure and improving the safety and reliability of the suspended tunnel, and also facilitate long-term use of cables and foundations anchored on a seabed or a riverbed; the construction risk is lower and costs are lower, effectively saving construction costs and being easy to implement and promote.
