Study On Dynamic Response For The Cable Of Submerged Floating Tunnel

Being an original tunnel style, Submerged Floating Tunnel has aroused many countries'attention to it after Hakkaart from Norway applied patent in 30 ages of last century. Althoughthere is still not any project dive into building, the research has indicated sufficiency that thisstructure has largeness competition power at solving the cross-sea traffic problem, protectingenvironment and reducing the cost of project, at the same time, it also reflect that there arestill many problems need construction and exploration for this project. Just at this background,I choose the dynamical analysis for the cable of SFT at the condition of sea, expect tocontribute my little strength for the realization of this project.This dissertation introduces some conceptions and general situation of research anddevelopment of SFT at first, and then introduces the cable specially. According to thecharacteristic of environment and force, choose the cable of cable-stayed bridge and the leg oftension leg platform as references. Based on the analysis and comparison of them and theadvisement of the particularities of the cable of SFT, established the simple calculate modelof the cable of SFT. Take the results of the analysis for the force the cable endured asfoundation, list the equation for the movement of cable, calculate and analysis the modelresponse of displacement, and also particular analysis and explore some important problemswhen simplify and calculate the model. At last, calculate and analysis the dynamic shearingforce and bending moments for the cable.According to the exploration of dynamic response for the cable of SFT in thisdissertation, get some available results for the research of SFT, provide some numerical valuefor the model experiment in the future, and also provide relevant contribution for the deeperresearch of SFT in the future.
