软地层(路基)在受到重载和重复(循环)列车加载时可能变得不稳定。本项目旨在研究铁路路堤下软基土壤不排水不稳定的原因和机制,并评估预制垂直排水沟(PVDs)在稳定此类土壤中的有效性。PVDs在提高履带性能方面的作用将通过严格的数学技术进行量化,以补充基于计算机的数值模型,该模型可以通过实验室和现场数据进行验证。它将为准确预测长时间列车负荷下软地基的长期沉降提供切实的结果,同时延长现代铁路基础设施的寿命。
英文摘要
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.
