项目摘要

Lifeline infrastructure - for example, bridges, dams, flood defences, ports, marine wind farms etc - in river, costal or marine environments is subjected to complex loading regimes arising through combinations of hydrodynamic and geotechnical effects. River or tidal currents and waves may induce structural loadings and sedimentological and / or geotechnical responses that can ultimately lead to severe damage or structural failure. Changing patterns of climate and infrastructure use mean that the compound effect of potentially two or more destabilising mechanisms is becoming increasingly complex and difficult to predict. However, despite their critical role in the resilience of lifeline infrastructure systems, these complex interactions remain largely under-researched. The resulting lack of understanding may lead to unnecessary costs or preventable failure of vital pieces of infrastructure. The aim of this project is to develop REAL, a novel experimental facility that will revolutionise research in submerged infrastructure by enabling comprehensive multi-phenomena testing. Creation of this unique facility will require the purchase of equipment comprising a large tilting flume, systems for water pumping and storage, wave generation and absorption, sediment feeding, recirculation and separation and instruments for detailed measurement of water velocities. These systems will be fully integrated and automated to reproduce scenarios representative of real-world conditions at unprecedented levels of realism. The research enabled by the facility will pave the way to novel approaches to the design and construction of future infrastructure systems that are both resilient and cost effective.

生命线基础设施 - 例如，桥梁，大坝，防洪，港口，海洋风电场等 - 在河中，沿海环境或海洋环境受到复杂的载荷状态，通过水力动力和岩土技术效应的组合产生。河流或潮流和波浪可能会诱导结构载荷以及沉积学和 /或岩土技术反应，最终会导致严重的损害或结构性故障。气候和基础设施使用的变化模式意味着，潜在的两种或多种不稳定机制的复合效应变得越来越复杂且难以预测。然而，尽管它们在生命线基础设施系统的弹性中起着至关重要的作用，但这些复杂的相互作用在很大程度上仍然不足。由于缺乏理解可能导致不必要的成本或至关重要的基础设施失败。该项目的目的是开发一种新型的实验设施，该设施将通过启用全面的多酚测试来彻底改变淹没基础设施的研究。创建这个独特的设施将需要购买包括大型倾斜水槽的设备，用于水抽水和储存的系统，波浪产生和吸收，沉积物喂养，再循环和分离以及用于详细测量水速度的仪器。这些系统将被充分整合并自动化，以在前所未有的现实主义水平下代表现实世界条件的情景。该设施实现的研究将为设计和构建未来基础设施系统的新颖方法铺平道路，这些基础设施既有弹性又具有成本效益。
