Mud pumping under rail tracks is identified as the most frequent issue causing the degradation of rail tracks and increasing their ongoing maintenance cost across Australia and worldwide. This project aims to further the understanding of mud pumping mechanisms across different scales. A novel combined experiment-computational approach will be developed to observe, analyse and link different material properties and external conditions governing the mud pumping process. It will lead to better criteria for mud pumping and numerical tools for field scale failure analysis and risk assessments. The expected outcomes include the enhanced capability to assess the integrity and stability of rail tracks and better design criteria against mud pumping.

铁轨下的泥浆被确定为最常见的问题，导致铁轨退化，并增加了整个澳大利亚和全球的持续维护成本。该项目旨在进一步了解不同尺度上的泥浆抽水机制。将开发一种新型的实验计算方法，以观察，分析和连接不同的材料特性以及管理泥浆抽水过程的外部条件。这将为泥浆抽水和数值工具提供更好的标准，用于现场量表故障分析和风险评估。预期的结果包括评估铁轨完整性和稳定性的增强能力以及针对冰泵的更好设计标准。
