This project aims to further the understanding of internal soil erosion across different spatial and temporal scales. Internal soil erosion is the most frequent cause of failures of water retaining structures. An approach combining advanced X-ray techniques with particle based methods will be developed to observe, analyse and link different material properties and external conditions governing the erosion process. This will lead to better criteria for soil erosion and numerical tools for field scale failure analysis and risk assessments. The expected outcomes of this project include enhanced capability to assess the integrity and stability of earth structures and better design criteria against erosion.

该项目旨在进一步了解不同时空尺度的内部土壤侵蚀。内部土壤侵蚀是挡水结构失效的最常见原因。将开发一种将先进 X 射线技术与基于粒子的方法相结合的方法，以观察、分析和链接不同的材料特性和控制侵蚀过程的外部条件。这将为土壤侵蚀提供更好的标准，并为现场规模失效分析和风险评估提供更好的数值工具。该项目的预期成果包括增强评估土结构完整性和稳定性的能力以及更好的抗侵蚀设计标准。
