Background
At present, two main water-area-crossing traffic modes, namely a river-crossing tunnel and a cross-channel have obvious defects. The bridge construction cost of the suspension bridge rises along with the length of the bridge in an exponential function, and the investment is very large; and the bridge is built above the water surface, which influences the navigation of the ship. In the submarine (river bottom) tunnel, when the seabed is deep, a long guide pipe section is needed for entering the submarine tunnel, otherwise, the inclination of the pipeline is large when entering, and the submarine (river bottom) tunnel is not beneficial to driving. In particular, when the subsea geological structure has significant defects, it can make construction difficult or even impossible.
Currently, there is a new method of cross-sea transportation, which is to construct a floating tunnel bridge in water, and the archimedes bridge is a tubular tunnel floating on the water bottom, and supports the weight of the tunnel by means of buoyancy, which is named by the archimedes principle. In order to avoid influencing water traffic and being influenced by weather, the tunnel is built under water, but in order to avoid bearing excessive water pressure, the tunnel is usually built at a depth of 20-50 meters. To maintain the depth in the water, the tunnel is secured with cables and pontoons to prevent it from being too shallow or too deep. The Archimedes bridge has three support modes of a float type, a rivet cable type and a rigid pile type. The conventional float-type suspension tunnel is only vertically restrained greatly, and under the action of wave current load, tsunami, earthquake and accidental explosion impact load, the float-type suspension tunnel can swing back and forth to generate large lateral displacement, so that the driving comfort degree in the suspension tunnel is greatly influenced, and even the vehicle is caused to turn on one side to cause serious safety accidents.
