The rail network in Australia provides a major transport route for commuters as well as transportation of goods. The subgrade of railway track should provide adequate support for the overlying ballast and capping layers. Hence, a poor subgrade always results in track problems associated with uneven track, fouled ballast, and misalignment of the track. This project will investigate in detail the fundamental mechanisms and key parameters involved in the improvement of subgrade soil by injecting lime-flyash slurry. This project will develop an improved design procedure for lime-flyash slurry injection in the field based on experimental and numerical modelling.

澳大利亚的铁路网络为通勤者和货物运输提供了主要的运输路线。铁路轨道路基应对上覆道碴和覆盖层提供足够的支撑。因此，不良的路基总是导致与不平坦的轨道、污染的道碴和轨道的不对准相关联的轨道问题。本计画将详细探讨二灰灌浆改良路基土的基本机制与关键参数。本项目将根据实验和数值模拟，开发一种改进的现场二灰浆注入设计程序。
