This project aims to develop a new cost-effective maintenance technique by applying laser cladding to enhance the characteristics of new rails and track components and repair damaged ones, so as to ensure their structural integrity and improve the performance of rail infrastructure. This project expects to generate new knowledge in the area of railway maintenance using the innovative and interdisciplinary laser cladding technology. Expected outcomes of this project are crucial for manufacturers and operators of railway networks to develop and improve their railway maintenance strategies. This should provide significant benefits, such as extending lives of rails and special track components, and reducing wheel squeal and flanging noise.Read moreRead less
Response of Vertical Drains in Soft Subgrade under Cyclic Rail Loading. Soft formations (subgrade) can become unstable when subjected to heavy and repeated (cyclic) train loading. This project aims to investigate the cause and mechanisms of undrained instability of soft subgrade soil beneath rail embankments, and to assess the effectiveness of prefabricated vertical drains (PVDs) in stabilising such soils. The role of PVDs to enhance track performance will be quantified via rigorous mathematical ....Response of Vertical Drains in Soft Subgrade under Cyclic Rail Loading. Soft formations (subgrade) can become unstable when subjected to heavy and repeated (cyclic) train loading. This project aims to investigate the cause and mechanisms of undrained instability of soft subgrade soil beneath rail embankments, and to assess the effectiveness of prefabricated vertical drains (PVDs) in stabilising such soils. The role of PVDs to enhance track performance will be quantified via rigorous mathematical techniques complementing a computer-based numerical model, which can be validated by laboratory and field data. It will deliver tangible outcomes for accurately predicting the long-term settlements in soft foundations over prolonged train loading while extending the life span of modern railroad infrastructure.Read moreRead less
