Research On Dynamic Demonstration For Submerged Floating Tunnel Underwater Working Environment

The submerged floating tunnel, an innovative structural typology, is used to cross waterway, such as strait, lake, fjord, etc. The submerged floating tunnel is suspended above the sea floor, anchored with a support system by anchoring to the water bed. Due to the major benefit of the short passing time, very low environmental impact, the freedom of choosing construction site, and environmental protection, etc, the submerged floating tunnel is attracting more and more attentions form various countries and researchers.Because of environment of the submerged floating tunnel in the ocean, the main load of structure comes from the ocean currents. This paper introduces some basic theories of ocean current in brief and analyzes the function of the wave and water, flow to the submerged floating tunnel simultaneously introduces some basic theories and equations of the fluid flow field and analyzes motion feature of the turbulent flow and the flow field around the submerged floating tunnel. On the basis, using the technique of the finite element method, this paper deals with the structure of the submerged floating tunnel and the water flow by the Fluid solid Coupling analysis way and simulates the flow field around the submerged floating tunnel. Then some conclusions the of the deformation rule of the structure of the submerged floating tunnel and the flow field variation between different flow rate can be draw.Because the submerged floating tunnel is built in the submarine, everything is unknown. In order to find out the working environment of the underground space in the submerged floating tunnel, on the basis of the numerical simulation on the flow field around the submerged floating tunnel, the Dynamic Demonstration on the submerged floating tunnel is developed with 3ds max and 3ds MAXScript language as the platform, to give designers and builders some feedback on the state of construction, development status of the tunneling and the flow field around the structure in the form of graphics and images, which can undoubtedly be used to better guide design and construction. The modeling of two—dimensional Graph is realized in the AutoCAD, the rending and animation of three-dimensional image in the 3ds max, the simulation for fluid in the 3ds Glu3d and the dynamic manager is gained through programming of the 3ds MAXScript language.
