Development of cyclic loading models for application in offshore geotechnics

海洋结构基础对重复(循环)荷载的响应是近海岩土工程中一个关键但仍未被充分了解的领域，其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，将建立一个用于模拟循环行为的最终框架。利用这一新方法，将发展数值模型，以处理从土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。将评估它们在海上设计问题上的应用(可再生能源以及传统的石油和天然气应用)。还将提出对现行国际准则的建议。

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.
