Abstract

Shaking table model tests were performed to reproduce the dynamic behavior of a gravity quay wall and a pile-supported wharf which were damaged during the Kobe earthquake in 1995. The results of the model tests were compared with field measurements and with the results of previous model tests. The displacements of the model quay wall were only one third of that of the prototype, whereas the deformation state of the model was similar to that of the prototype. The displacements of the model pile-supported wharf were about two thirds of that of the prototype and the locations of the maximum moments at the model pile were similar to the buckling locations of the prototype piles.

1995년 고베지진에 의해 피해를 입었던 중력식 안벽구조물과 잔교식 안벽구조물의 동적 거동을 재현하고, 분석하기 위하여 소규모 1-g 진동대 모형시험을 수행하였다. 1989년 Iai가 제안한 상사법칙을 이용하여 진동대 모형시험 결과를 원형크기의 것으로 환산하여 현장계측 결과와 비교하였다. 그 결과, 중력식 안벽구조물의 변위는 현장계측 결과의 약 1/3 정도 발생하였고, 벽체의 변형 형상은 원형과 유사하였다. 잔교식 안벽구조물의 변위는 현장계측 결과의 약 2/3 가 발생하였고, 말뚝에 발생하는 최대모멘트의 위치와 원형말뚝의 파괴위치는 잘 일치하였다.
