The Mechanical Behavior of Steel Circular Caisson by Horizontal Load

水平載荷에 따른 鋼製圓筒 케이슨의 力學的 擧動

Model tests were performed to examine the mechanical behavior of steel circular caisson by horizontal load. It was generally found that displacements and bottom pressure of the caisson model were increased rapidly at the local plastic load. The maximum displacement was measured at the loading point, whereas the less displacement was measured at the upper part of the caisson model. The bottom pressure was getting higher, as it was nearer the loading side. Furthermore, the increase ratio of the bottom pressure was higher as the load was increased.

강제원통케이슨의 역학적 특성을 규명하기 위하여 수평하중에 의한 실내모형실험을 수행하였다. 전체적인 경향으로서 셀강판에 국부적인 소성변형이 발생하는 하중 레벨에서 변위와 저면토압은 급격히 증가함을 알 수 있었다. 변위는 재하점위치에서 가장 크고 케이슨 상단부의 변위는 작은 값을 나타내었다. 저면토압은 재하면에 가까울수록 크며 하중 증가에 따른 토압증가율 또한 재하면에 가까울수록 커짐을 알 수 있었다.
