Abstract

This study evaluates the seismic performance of road tunnels designed before the provisions for seismic design of tunnels were first established in 1999. Extensive design data and site investigation reports are investigated to select tunnels sections that are considered to be most susceptible to seismically induced damage under earthquake loading. Detailed analyses are performed on selected tunnels. The methods used are method of displacement and dynamic analysis. In performing the method of displacement, which is a type of pseudo-static analysis method used for underground structures, full domain and reduced domain modeling were used. The dynamic analyses are performed using finite difference method and using nonlinear constitutive model. Comparisons show that the reduced domain method of displacement match very closely with the dynamic analysis, demonstrating that it is the most suitable method for evaluating the seismic performance of road tunnels built in rocks. It is also shown that road tunnels, for which seismic design were not applied, are safe under the seismic risks corresponding to an earthquake with a return period 1000 years. It is concluded that additional seismic retrofit of tunnels is not necessary.

본 연구에서는 터널에 대한 내진설계 기준이 처음으로 제정된 1999년 이전에 설계된 현재 운영중인 도로 터널의 지진에 대한 성능을 평가하였다. 이를 위하여 1999년 이전에 설계된 도로 터널 자료를 조사하였으며 이중에서 가장 지진에 취약할 것으로 예상되는 대표 단면을 선정하여 이들에 대한 정밀한 안전성 평가를 수행하였다. 사용된 해석방법은 응답변위법과 동적해석이며 모두 유한차분해석 프로그램을 이용하였다. 응답변위법은 전체영역과 축소된 해석 영역에 대한 해석을 수행하였으며 동적해석은 비선형 해석을 수행하였다. 해석 결과, 축소된 해석영역에 대한 응답변위법과 동적해석의 결과가 매우 유사한 것으로 나타났으며 내진설계가 적용되지 않은 터널들도 재현주기 1000년 지진에 대해서는 안전하며 추가적인 보강은 불필요한 것으로 나타났다.
