This project aims to develop a novel cost-effective and eco-friendly method to stabilise soil foundation for faster and heavier rail transport. The scientific knowledge of cyclic behaviour capturing localised and microscale evolutions of railway foundation will be advanced significantly via innovative physical modelling using iconic facilities with state-of-the-art sensors, and sophisticated numerical modelling. The project will yield a natural biopolymer-based solution for mud pumping railways, i.e., a critical issue causing substantial annual maintenance cost and poor transport efficiency in Australia and worldwide. The outcomes will greatly benefit transport infrastructure, mining, agriculture, environment and climate change remediation.

该项目旨在开发一种新的具有成本效益和环保的方法来加固地基，以实现更快、更重的铁路运输。通过使用带有最先进传感器的标志性设施的创新物理模型和复杂的数值模型，捕捉铁路地基局部和微尺度演变的循环行为的科学知识将得到显著提高。该项目将为泥浆泵送铁路提供一种基于天然生物聚合物的解决方案，这是一个关键问题，在澳大利亚和世界范围内导致每年的维护成本和运输效率低下。这些成果将极大地惠及交通基础设施、采矿、农业、环境和气候变化补救。
