Dynamic response and structural integrity of submerged floating tunnel due to hydrodynamic load and accidental load

This paper generally describes the research advances on dynamical response and structural integrity of submerged floating tunnel (SFT) subjected to hydrodynamic load and accidental load, which were accomplished by a research team in the Institute of Mechanics, Chinese Academy of Sciences in recent years. By means of theoretic analysis, modeling, calculation and experimental investigation, the research team has achieved creative results in several aspects including: (1) ABB Selection and its environmental & geotechnical conditions for ABP design, (2) Dynamic characteristics of SFT due to wave and current loads, (3) Effects of SFT structural parameters on its dynamic response, (4) Geotechnical investigations and tension pile analysis, (5) Dynamic response of SFT due to seismic load and accidental load, (6) Effects of water and sea-water on high-cycle and very- high-cycle fatigue behavior for metallic materials, and (7) Design of ABP of Qiandao Lake and its structure analysis & strength assessment.
