Abstract

In the construction and operation of large marine structure, hazard risk analysis is one of important factors. Therefore, this paper investigates the hazard risk indexes and evaluates the risk level in the construction and operation of SFT on the basis of expert survey and Fuzzy analytic hierarchy process. Hazard risk is divided into natural hazard risk (earthquake, typhoon, tsunami, and ice collision) and human factor hazard risk (fire, explosion, traffic accident, ship or submarine collision). Also, the influence of hazard risk indexes on SFT was evaluated in tunnel tube, supporting system, ventilation tower, foundation, and connection part. As the hazard risk level of SFT is compared with those of bridge, underwater tunnel, and immersed tunnel, the intrinsic risk level of SFT was evaluated. Tsunami and earthquake had higher risk level in natural hazard risk, and the risk levels of fire and explosion were higher in human factor hazard risk. Hazard risk level of SFT was 1.4 times higher than immersed tunnel, and 3.2 times higher than bridge.

대형 해양구조물의 건설과 운영에서 중요한 항목 중의 하나가 재해위험도를 분석하고 평가하는 것이다. 이에 본 연구에서는 수중터널의 건설과 운영 시에 발생할 수 있는 재해 위험요소를 도출하고 퍼지 AHP(Analytic Hierarchy Process) 방법으로 이러한 위험요소의 수준을 파악하고자 하였다. 재해 위험도로는 자연재해 위험도와 인적재해 위험도로 구분하고 이러한 위험도 항목들이 수중터널에 미치는 영향을 전문가 설문을 통하여 조사하였다. 조사된 전문가 설문결과 데이터를 퍼지 AHP 기법으로 분석하여 재해위험도를 각 위험요소별로 정량화하였다. 또한, 수중 터널과 교량, 해저터널, 침매터널의 재해위험도 수준을 분석하여 수중터널이 가지고 있는 고유의 재해위험도 수준을 평가하였다. 재해위험도에서는 쯔나미와 지진이 가장 위험도 인식수준이 높았고, 인적재해 위험도는 화재와 폭발의 위험도 인식이 높은 수준이었다. 또한, 수중터널은 침매터널에 비해서는 1.4배, 교량에 비해서는 3.2배 위험도 인식수준이 높은 것으로 조사되었다.
