Abstract  With the development of the country's large-scale infrastructure, the demand for underwater tunnel construction is increasing; however, regarding the construction, operation and maintenance of underwater tunnel are more difficult, the tunnel durability needs to be concerned as well as the life-cycle design. This paper investigated the waterproof and durability measures of the Tokyo Bay Transverse Highway Tunnel, and proposed a comprehensive durability strategy of “multiple waterproof, multi-anticorrosion, and life-cycle design” for the construction of large diameter underwater tunnel. In addition, a life-cycle design method was established with the performance and cost as indicators, and was applied to evaluating of a submarine tunnel under four construction and maintenance plans. As the result, it was clarified that the plan of the high durable tunnel in the initial stage was the most beneficial, and the life-cycle design method was effective. Conclusively, the rational planning and design, scientific construction and maintenance of underwater tunnels could be foundationally supported by development of a life-cycle design system accounting for the economy, safety and environment.
