Abstract
The present Thesis is organized in 10 chapters. In particular Chapter 1
gives a general overview of the modern solutions and technologies available
in the field of waterway crossings, introducing briefly the revolutionary
concept of Submerged Floating Tunnel.
Chapter 2 provides a deeper insight into the main characteristics of this
innovative structural solution for waterway crossings: first its structural
features are described and the relevant loading conditions discussed,
subsequently the main advantages of the SFT with respect to the traditional
crossing solutions, such as the Cable Supported Bridges and the Underground
and Immersed Tunnel are described.
Chapter 3 traces the history of the SFT, starting from its first proposal
made in 1969 for the Messina Strait crossing, describing all the feasibility
studies and preliminary designs developed all over the world in the following
years. This Chapter is concluded by a description of the Sino-Italian
cooperation programmes, involving among the other partners the University
of Naples “Federico II”, which led to a feasibility study relative to the
crossing of the Jintang Strait (P.R. of China) with a SFT and to the complete
design of the first SFT full-scale prototype, planned to be realized in the
forthcoming years in the Qiandao Lake (P.R. of China). A potential SFT
crossing in the Pulau Seribu Archipelago (Indonesia), preliminary studied in
the last years by the research team headed by Prof. Mazzolani, is also briefly
illustrated.
Chapter 4 explains in the detail of the various aspects faced in the design of
the Archimedes Bridge prototype. The features of the selected location and the
structural scheme are illustrated. The structural analyses aimed at
investigating the prototype behaviour under the environmental loads are
discussed. The conception and the design of the constructional details are
presented. Finally, the fabrication and erection procedures are briefly
described.
Chapter 5 provides a description of the structural models which can be used
to analyse the SFT structural behaviour: the beam on elastic foundation, which

can be used in the preliminary phase of the design, and a SFT Finite Element
Model.
Chapters 6 and 7 are devoted to the study of the response of the SFT to the
main environmental loads to which is subjected: the hydrodynamic actions
due to the presence of waves and currents and the earthquakes. Numerical
analyses are carried out with the Finite Element analyses aimed at the
understanding of the SFT structural behaviour and at the definition of the
optimal structural configurations.
In Chapter 8 potential SFT solutions developed for the Messina Strait and
Gibraltar Strait crossings are illustrated and a technical-economical
comparison with the Suspension Bridges designed for the same locations is
made.
Chapter 8 describes a simple procedure for a quick comparison of the SFT
and CSIB solutions with the Cable Supported Bridges one, providing useful
curves highlighting the conditions under which the former ones are more
competitive than the latter ones.
Finally, in Chapter 9 the future steps and challenges to be faced in the
development of Submerged Floating Tunnel are presented. An alternative
typology of floating tunnel is introduced too: the Cable Supported Immersed
Inversed Bridge (CSIB), which is conceived as a combination of the
submerged floating bridge concept with the cable system configurations and
features several advantages also with respect to the “traditional” SFT solution.
