Abstract

In the design phase of sea-crossing bridge projects, ship collision problem is mostly participated in decision of substructure section and it would be performed by risk assessment and impact simulations. Ship collision risk is assessed by probability model which is similar to method II of Guide Specification and Commentary for Vessel Collision Design of Highway Bridge(AASHTO, 2009). However, several factors used in the applicable code are limited to inland waterways or have many local characteristics. Accordingly, it should be needed judgement of engineer or referred to related criteria, research finding. In this study risk assessment for In-cheon bridge and review of existing substructure's impact risk and resistance capacity are performed using the 2010's ship passage data. And then consideration regarding to presumption and applied instance of factors needed for risk assessment and related research findings are performed on the basis of AASHTO Guide's Method. As a result of study, adequate variable region of factors needed for risk assessment is defined and sensitivity analysis for appropriate region is performed. Consequently, factors that should be applied carefully or needed for direct analysis of local data are confirmed. This research could be fundamental material to risk assessment related to design for sea-crossing bridge taken into account ship collision.

본해상교량 프로젝트의 설계단계에서 선박충돌 문제는 주로 교량 하부구조의 단면 결정에 관여하게 되며, 위험도 평가와 충돌 시뮬레이션 등을 통해 설계를 수행하게 된다. 선박의 충돌위험은 다양한 확률모델에 의해 평가되며 대체로 AASHTO Guide(2009)의 Method II와 유사하다. 그러나 해당기준에서 사용되는 일부 요소는 내륙수로에 국한되어 있거나 지역적인 요인이 강하여 설계자의 판단이 요구되므로 관련 기준이나 연구결과 등을 참고하여 결정해야 한다. 본 연구에서는 2010년 선박운항데이터를 사용하여 인천대교에 대한 위험도평가를 수행하고 기존 하부구조 및 방호구조물에 대한 위험도 및 내충돌 성능을 검토하였다. 그리고 AASHTO Guide의 Method II를 기준으로 하여 위험도평가에 필요한 요소들의 추정 방법과 적용 사례, 관련 연구결과에 대한 고찰을 수행하였다. 이로부터 위험도평가에 필요한 요소들의 적절한 가변영역을 정의하고 해당 구간에 대한 민감도 분석을 수행하였으며 설계단계에서 설계자가 주의하여 적용해야 하거나 지역적인 데이터의 직접 분석이 필요한 요소들이 확인되었다. 이번 연구는 해상교량에 대한 선박충돌을 고려한 설계시 위험도 분석과 관련하여 기본적인 참고자료가 될 것으로 판단된다.
