Calculation and Analysis of Horizontal Force of Submerged Floating Tunnel
摘要
Submerged floating tunnels have great advantages for crossing fjords and deep sea areas. The floating tunnel is floating at a position 30m below the surface of the sea, and it has to continuously bear the impact of the water flow. Under the assumption of vertical balance, the calculation of the horizontal force of the floating tunnel can provide a reference for the actual project. First, establish the tunnel and watershed model in ICEM CFD; import the model into FLUENT for calculation, and obtain the horizontal force changes under three different environmental flow rates; finally, analyze and compare the horizontal displacement changes caused by the three results on the structure in ANSYS And come to a conclusion. The results show that under the action of three different flow rates, the underwater floating tunnel can better resist the impact of water flow and reach a state of horizontal equilibrium, which can provide a certain theoretical reference for actual engineering.
