Study on Composition and Simulation Analysis of Traffic Loads in Submerged Floating Tunnels

For Submerged Floating Tunnels (SFTs) under operation, traffic load is a variable fundamental load and an important part of various loads they bear. The traffic loads of SFTs involve many factors such as vehicle parameters, vehicle speeds, road conditions, underwater conditions, etc. Based on the vehicle traffic characteristics and the structural properties of SFTs and with a comprehensive consideration of the influence mechanism of traffic loads, this paper puts forward an expression of traffic loads under the action of wave forces through an analysis of the composition and influence factors of traffic loads in SFTs. Furthermore, it analyzes the influence degrees and application range of such traffic loads by means of a numerical analysis, which may serve as a reference for related research on dynamic response of SFTs.
