Abstract


Floating Tunnel (Submerged Floating Tunnel) referred to \Floating Tunnel there are other types of traffic structure unparalleled technical and economic advantages: on structures such as the surrounding environment has little effect on water depth and seabed topography, geological conditions, adaptable , reducing the approach roads and land transport links the length and slope , can reduce construction costs and pollution. Immersed tube tunnel , offshore platforms and other structures related to the rapid development of technology , making the submerged floating tunnel construction work has had a certain foundation. As an innovative technology, submerged floating tunnel has become competitive with conventional traffic technology an extremely attractive technology options. In this paper, unsteady flow under the action of a single span Floating Tunnel cross- flow vortex induced dynamic response and reliability issues carried out some preliminary theoretical studies , the launching of a research work are: 1 . Elaborated currents causes , types, statistical laws , focusing on the floating tunnel suffered calculation method and load currents VIV vortex-induced lift mechanism and calculation model . 2 would be simplified into a single span suspension tunnel ends simply supported Euler-Bemoulli beam, derived with a single vortex shedding frequency, the effect of vortex-induced lift pipe bending vibration of partial differential equations, and the use of partial differential equations method of separation of variables into ordinary differential equations to obtain floating tunnel each order natural frequency and modal response ( displacement , bending moment , shear ) analytical solution . Found by calculating the first-order response plays a dominant role in research on the dynamic suspension tunnel can only be a first-order dynamic response analysis . 3 Consider the randomness of the calculation parameters , assuming lift coefficient Q and velocity V normal distribution , using Monte Carlo (Monte-Calor) method to obtain the amplitude of vortex-induced lift the probability distribution for the extreme type Ⅰ , unit of time (60s) midspan moment magnitude span displacement amplitude probability distribution for the exponential distribution . 4 discusses the structural limit state equations established method , and calculate the corresponding reliability.
