Understanding vibratory piles in sand: installation and lateral response

本课题旨在解决振冲桩设计中的不确定性问题。这种替代冲击桩的方法不仅安装速度更快，而且不需要降低噪音。该项目希望通过整合创新实验和数值模拟的结果，产生关于砂土中安装过程对在用桩响应影响的新知识。这对于海上风力涡轮机等高度敏感的结构尤其重要，因为海上风力涡轮机在全球能源供应中所占的份额正在迅速增加。预期结果包括砂中振冲桩的实用建议。通过释放振冲桩作为降低海上风电场成本的可行方法，这将提供相当大的好处。

This project aims to address uncertainties in the design of vibro-driven piles. This promising alternative to impact-driven piles offers faster installation and requires no noise mitigation. The project expects to generate new knowledge of the effect of the installation process in sand on in-service pile response by integrating findings from innovative experiments and numerical modelling. This is particularly important for highly sensitive structures such as offshore wind turbines, which provide a rapidly increasing share of global energy supply. Expected outcomes include practical recommendations for vibro-piles in sand. This should provide sizeable benefits by unlocking vibro-piles as a viable method to reduce offshore wind farm costs.
