Study on the Main Influence Factors of Traffic Loads in Dynamic Response of Submerged Floating Tunnels

As the main variable loads during the service stage of Submerged Floating Tunnels (SFTs), traffic loads is an important part in the studies of SFTs' dynamic response. On the basis of the characteristics of moving vehicles and the structural characteristics of SFTs, this paper puts forward the calculation formula of traffic loads, with a comprehensive consideration of different influencing factors. In this paper, in order to obtain the degrees of influence of such factors on the calculated values of traffic loads and the dynamic response of SFTs and the weight of each factor, the author uses the orthogonal experiment method and the analytic hierarchy process, combining them with a simulation of the finite element software. It is expected to provide reference for related researches on SFTs.
