Abstract

In this study, the seismic response of cut-and-cover box tunnels is evaluated from pseudo-static analyses and the fragility curves are derived. A series of site profiles were used to evaluate the effect of soil conditions. A total of 20 ground motions were used. The fragility curves were developed as functions of peak ground acceleration for three damage states, which are minor, moderate, and extensive states. The damage indices, defined as the ratio of the elastic moment to the yield moment, correlated to three damage states, were used. The curves are shown to greatly depend on the site profile. The curves are further compared to those derived in previous studies. The widely used empirically derived curves are shown not to account for the site effects, and therefore underestimate the response for soft sites.

본 연구에서는 박스형 개착식 철도 터널의 지진 응답을 유사정적 프레임 해석으로부터 평가하였으며 취약도 곡선을 도출하였다. 지반의 영향을 평가하기 위하여 다양한 이상화된 주상도를 사용하였으며 20개의 계측지진기록을 적용하였다. 기존 연구에서 제시된 탄성 모멘트와 항복 모멘트 비로 정의된 손상지수를 사용하여 Minor, Moderate, Extensive 손상상태에 대한 취약도 곡선을 각각 최대지반가속도의 함수로 적용하였다. 연구 결과, 지반 조건은 취약도에 큰 영향을 미치는 것으로 나타났으며 이를 고려하는 곡선의 개발이 중요한 것으로 나타났다. 개발된 취약도 곡선은 기존의 연구에서 도출된 곡선들과 비교하였다. 기존에 제시된 경험적 취약도 곡선은 지반조건의 영향을 고려할 수 없으며 특히 연약 지반에서는 취약도를 과소예측하는 것으로 나타났다.
