Abstract
Various methods have hitherto been proposed for interlocking adjacent caissons to enhance stability of harbor structures to resist the abnormally high waves [1],[2]. Among the methods, it was studied the method based on an open-cell caisson by filling materials in an inter-cell formed by two facing open-cells which consist of transverse walls. It is necessary to investigate the shear behavior of an inter-cell to secure the stability using calculating shear forces under wave loadings. In this paper, structural behaviors of open-cell caisson evaluated by FE analysis using commercial program [3] including stress distribution of filling materials, distribution subgrade reaction force, behavior evaluation of global system etc., [4],[5]. According to the analysis result, the open-cell caisson has good performance compare with the conventional caisson type. It was applicable in the assumption that filling materials was uniformly distributed in inter-cells, and further studies were worth consideration on other conditions including foundation. by filling materials in an inter-cell formed by two facing open-cells which consist of transverse walls.
