Research on sinking and leveling control technology of tripod bucket foundation in sand

High capacity wind-turbines are increasingly installed offshore and further away from the coast, where strong foundations required, their installation is challenging. The so-called multi-bucket foundation a promising candidate to be used for such scenarios. However, sinking control technology, which commonly ease installation, not very mature. In this paper, series of theoretical studies tests carried out investigate process wide-shallow tripod bucket (WTBF). First, mechanism seepage-failure WTBF at different depths investigated using both empirical formulas experiments. addition, optimal method calculate/predict in sand value range kfc coefficient determined. Then, an experiment determine maximum adjustable initial tilt-angle (based on seepage failure control) conducted. This enables improvement/determination index methods as well during process. Finally, automatic system leveling foundation, uses dual-index (seepage failure, angle) developed. feasibility approach verified through
