쉴드터널 공법은 도시의 지하철도, 상ㆍ하수도, 전기ㆍ통신 등을 설치하기 위한 터널 건설 수단으로 활용되고 있다. 일본은 1960년경부터 도시의 근대화를 추진하면서 infrastructure를 정비하였으며 이에 따라 쉴드터널 공법의 적용이 급속히 증대하였다. 도시의 지하에 터널을 건설함에 있어 가장 중요한 것은 기존 도시구조물에 대한 영향을 최소로 줄여서 도시기능을 보전하는데 있다.(중략)

Recently, tunnel technology in Korea has shown various achievements such as long tunnel and large section by tunnel construction using TBM in Korea and abroad. Especially subsea tunnels are frequently designed and constructed. The Ga-deok subsea tunnel was completed in December 2010, and the Incheon North Port Tunnel was opened and operated in 2017, and the Bo-ryeong subsea tunnel between Dae-cheon Port and Won-san Island will be completed in 2021. In foreign countries, many subsea tunnels have been constructed and operated in such as Norway and Japan. The main technical problem in the construction of subsea tunnel is to secure stability due to high water pressure conditions and large-scale seawater inflow in fault zones and weak zones. In this paper, various risk factors and solutions are described in the subsea tunnel planning of national road 77 construction work between Abhae and Hwawon.

Subsea tunnel needs to be built over 50 km long to connect between nations and continents. However there are only 19 tunnels longer than 5 km until recently. And there is no history of constructing and operating tunnel longer than 50 km. In Korea, subsea tunnels with a length of more than 50 km are being planned, such as Korea~Japan, Korea~China, Honam~Jeju subsea tunnels. Because of the geographical conditions of Korea, most of these tunnels are inter-contry tunnels. So technology preemption for the subsea tunnel construction is getting more and more important. Most of these subsea tunnels are ultra-long tunnels under high water pressure conditions. So new technologies are required such as ventilation and disaster prevention of high-speed tunnels, securing of structural stability under high pressure conditions, and pressure reduction in high-speed conditions. These technologies are different from those of ground tunnels. Therefore, this paper describes the ultra-long subsea tunnel design under high water pressure of maximum 16 bars through the Honam (land) - Jeju (island) virtual subsea project. We proposed a reasonable solution to various problems such as securing structural stability in high pressure condition and ventilation disaster prevention system of ultra long-tunnel.

Various tunnels such as road, subway, and railway are under construction and operation. Various types of linings are used for structural stability of tunnel structures, and concrete segment linings are mainly installed in TBM tunnel construction. In this paper, when a fire occurs in a tunnel, the impact on the concrete segment lining, which is the structure in the tunnel, and related standards, fire resistance evaluation and fire resistance method are investigated through literature review and related contents are presented. Through this, it is intended to provide an information for practitioners to secure the safety of concrete segment linings against tunnel fires.
