正确认识土壤-水的相互作用,对于洪泛区的可持续发展,以及阻止黄铁矿土壤氧化引起的酸性矿山废水是至关重要的。可渗透反应屏障(PRB)为中和酸化地下水提供了一种经济高效的解决方案。该项目旨在通过将岩土基础知识与综合水文-生物-地球化学过程相结合来量化PRB颗粒介质的堵塞潜力。将通过岩土实验室和现场测试来评估随时间变化的堵塞情况。预期成果是改进的PRB设计方法和完善的岩土现场监测,以提供显著的行业效益,如矿场修复、提高生产率和基础设施寿命。
英文摘要
Proper understanding of soil-water interaction is vital for sustainable development of floodplains, and to halt acid mine drainage caused by the oxidation of pyritic soil. Permeable reactive barriers (PRB) offer a cost-effective solution to neutralize acidified groundwater. The project aims to quantify the clogging potential of PRB’s granular medium by coupling geotechnical fundamentals with integrated hydro-bio-geochemical processes. Time-dependent clogging will be evaluated through geotechnical laboratory & field testing. Expected outcomes are enhanced PRB design methods and sound geotechnical field monitoring to provide significant industry benefits, such as mine-site rehabilitation, increased productivity and infrastructure longevity.
