Abstract

Seismic risk analysis was performed based on the total stress and effective stress of caisson type quay wall and pier type quay wall. In order to consider the effective stress effect, the pore pressure of the ground was distributed, using Byrne(1991) simple formula to estimate parameter and applied to the finn model. Through the results of seismic risk analysis according to the total stress and effective stress analysis method, the necessity of effective stress analysis in the seismic design of the quay wall installed on the soft ground was confirmed.

전응력 및 유효응력기반으로 케이슨식 안벽과 잔교식 안벽의 지진위험도 해석을 수행하였다. 유효응력효과를 고려하기 위해 지반의 간극수압을 분포시켰으며, Byrne(1991)이 제안한 간편식을 이용하여 매개변수를 산정하고 이를 Finn 모델에 적용하였다. 전응력 및 유효응력 해석기법에 따른 지진위험도 결과를 통해 연약지반에 설치된 안벽의 내진설계 시 유효응력해석의 필요성을 확인하였다.
