Physics-informed hydrodynamic model for clay across scales

本项目旨在通过将微观和介观机制的直接观察与严格的物理原理相结合，建立粘土宏观行为的预测模型。该项目希望使用新颖的x射线和光学方法来跟踪粘土聚集体在不同载荷和湿度下的膨胀或收缩。一个关键的预期结果是建立一个稳健的粘土水动力模型，使所观察到的现象合理化。预期的结果包括对粘土动力学的准确预测，要么在滑坡时快速，要么在干燥和潮湿时缓慢。由于澳大利亚大部分地区经历干旱和洪水，该项目应该有利于位于粘土上的关键基础设施的寿命和安全性。

This project aims to develop a predictive model for the macroscopic behaviour of clay by combining direct observations of microscopic and mesoscopic mechanisms with rigorous physical principles. The project expects to track clay aggregates as they expand or shrink under variable loads and moistures using novel X-ray and optical methods. A key anticipated result is the development of a robust hydrodynamic model for clay that rationalises the observed phenomena. Expected outcomes include the accurate predictions of clay dynamics, either fast during landslides or slow under drying and wetting. As much of Australia experiences droughts and floods, this project should benefit the longevity and safety of critical infrastructure situated on clay.
