... ABSTRACT This paper aims to investigate the dynamics of a submerged floating tunnel (SFT) with inclined taut mooring lines under tsunami-like freak waves. The SFT is modeled using the lumped-mass line model and the dummy-connection-mass method to examine the hydro-elastic behavior...

... ABSTRACT Submerged floating tunnels (SFTs) are considered as one of the relevant concepts to replace ferry connection in the Norwegian Public Road Administration's plan to upgrade the E39 coastal highway. Current load including lift and drag force is one the most important factors challenging...

... ABSTRACT Submerged floating tunnel (SFT) is a new type of transportation infrastructure for crossing sea straits of relatively deeper water. Comparing with the fixed tunnel, the main challenge in designing a SFT is the stability maintaining in complex hydrodynamic environment, especially...

... ABSTRACT Deflection of the tube of submerged floating tunnel (SFT) under environmental loading such as current, long crest wave or even sea density variation as well as its vibration characteristic are of great interest to engineering researchers. In this paper, the simplified two-dimensional...

... ABSTRACT In this paper, the behaviors of the ground-tunnel interface of submerged floating tunnels (SFTs) and traditional bored subsea tunnels are investigated through numerical analyses. The analyses consider both permanent loads (self-weight, hydrostatic pressure, buoyancy etc...

... ABSTRACT In this study, time-domain dynamic analysis of a submerged floating tunnel (SFT) is carried out under wave and seismic excitations to evaluate the safety of a train passing through a tunnel. The in-house program is modified to simulate dynamics of the SFT and the train. The equation...

... ABSTRACT Effects of moving loads and wave excitations on a 900-m-long SFT (submerged floating tunnel) are presented and discussed. Floater-mooring coupled dynamic analysis is done by a time-domain numerical simulation program. Hydro-elasticity of the tunnel and mooring lines are considered...

... ABSTRACT This paper presents the dynamic response/global performance of two types of submerged floating tunnels (SFTs) under survival wave and seismic conditions. Time domain numerical simulations are performed by the commercial program, OrcaFlex. Three buoyancy to weight ratios (BWRs...

... function theory (SFT) has quickly become a preferable method to assess the wave kinematics because of the numerical and computational power evolution. The robustness and easy application to shallow water waves of the SFT, made it popular for practical applications. With fast results easy to apply directly...

... The submerged floating tunnel (SFT) is suitable for a connection method of deep and wide waterways. SFT is mainly floated by their buoyancy or supported by the columns. It is similar to floating bridges or immersed tunnels. In the construction and operation of large marine structure, hazard risk...

... ABSTRACT Many fixed crossing of waterways has been built, bridge, pontoon bridge, floating bridge, bored tunnels, and Immersed tunnels In the case of long distance between the shores, deep-water, hard sea state, and conventional structures are not feasible. The Submerged Floating Tunnels (SFT...
