The response of foundations for offshore structures to repetitive (cyclic) loads is a critical but still inadequately understood area of offshore geotechnics, with designs still usually based on simple modifications to monotonic loading conditions. In this project, a definitive framework for modelling cyclic behaviour will be established. Using this new approach, numerical models will be developed to address problems at all scales from fundamental constitutive behaviour of soils to macroscopic models for large foundation systems. Their application to offshore design problems (for renewable energy as well as traditional oil and gas applications) will be assessed. Recommendations to current international guidelines will also be made.

海洋结构物基础对重复（循环）荷载的响应是海洋岩土工程的一个关键领域，但尚未得到充分理解，设计通常仍基于对单调荷载条件的简单修改。在这个项目中，将建立一个明确的框架，模拟循环行为。使用这种新的方法，将开发数值模型，以解决从土壤的基本本构行为到大型基础系统的宏观模型的所有尺度的问题。将评估其在海上设计问题（可再生能源以及传统石油和天然气应用）中的应用。还将对现行国际准则提出建议。
