Abstract

This paper presents a study on the horizontal bearing performance of open-ended gravity-based foundations（OGBFs）for offshore floating photovoltaic （FPV）systems. In this study, a combination of numerical analysis and centrifuge model tests was conducted used to investigate the horizontal bearing behaviors of OGBFs in clay. The horizontal ultimate bearing failure mechanisms of OGBFs were identified, and the effects of embedment ratios, hole ratio, and various contact conditions on the bearing characteristics of OGBFs were examined. The results indicate that the horizontal bearing failure mechanisms of OGBFs is dominated by sliding failure. Under different hole ratios, embedment ratios, and contact conditions, failure mechanisms can be categorized into global sliding failure and partial sliding failure. Based on the analysis of failure mechanisms, an optimal hole ratio and a calculation method for the horizontal ultimate bearing capacity applicable to OGBFs are proposed.
