项目摘要

Reliable drainage solutions are critical for ensuring the long-term and cost-effective provision of railway infrastructure. Water plays a significant role in the degradation of railway infrastructure and can cause poor track geometry and accelerated deterioration of ballast, with high associated maintenance and repair costs which inevitably get passed on to the end-user. Excessive amounts of water may also cause catastrophic failure of railway infrastructure systems, which represent a real threat to public safety. Climate change is predicted to result in more extreme weather and flash flood events. The railway drainage systems will therefore be put under severe strain with increased likelihood of disruption to rail services. Much of the UK railway drainage infrastructure is old and in need of repair or replacement. However, the UK railway industry is experiencing significant growth in the number of passengers and the amount of freight carried, which reduces the opportunities available to carry out maintenance. In light of these issues, railway drainage system modernisation is considered to be a key factor for improving railway network safety and capacity, and ensuring the infrastructure's resilience to changing weather and climate events. This project focuses on providing novel and easily installed railway drainage solutions which make use of lightweight and cost-effective 'new materials'. 'New materials' includes those recently developed as well as materials that can be newly applied within drainage systems. The project will consider a range of materials for use in this application, such as Expanded Polystyrene (EPS) which is a lightweight and strong material with good chemical resistance. The project includes a range of experimental testing, including trials of a new material drainage system within a full-scale railway track model, as well as advanced small-scale physical modelling using the University of Nottingham geotechnical centrifuge. Numerical models will also be developed to gain a better understanding of the effects of key parameters within the drainage system. An important component of the project is the development of tools which will allow for the assessment of the full lifecycle costs of the developed new material drainage solutions. These tools have the potential to help railway operators make informed decisions relating to the selection of track and drainage system maintenance and repair solutions. Advanced tools will also be developed which will provide a better understanding of the inter-relationships between railway drainage performance and other railway systems, including other infrastructure assets and operation services. The project benefits from the involvement of experts from railway industry, including URS, a leading provider of engineering, construction and technical services within the railway sector, and ASPIN, who provide a range of consultancy services to the railway industry. The project will also benefit from access to information from Network Rail, the owner of the UK railway infrastructure, through proven links between the research team and representatives from Network Rail. The project fosters a multi-disciplinary approach to developing engineering solutions, with expertise from several technical areas, including geotechnics, transportation infrastructure design and performance as well as asset management.The successful completion of the project will allow the development of modern railway drainage solutions which incorporate new lightweight, easy to install, and cost-effective materials. The lifecycle cost assessment tools developed as part of this project will enable railway operators to make informed decisions about railway maintenance and repair, and ensure that end-uses of the railway get the best service possible.

可靠的排水解决方案对于确保铁路基础设施的长期和成本效益的提供至关重要。水在铁路基础设施的退化中起着重要作用，可能会导致轨道几何形状和镇流器的加速恶化，并具有高关联的维护和维修成本，这不可避免地传递给了最终用户。大量的水也可能导致铁路基础设施系统的灾难性故障，这代表了对公共安全的真正威胁。预计气候变化会导致更极端的天气和山洪事件。因此，铁路排水系统将处于严重的压力下，而对铁路服务的可能性增加。英国铁路排水基础设施的大部分都是古老的，需要维修或更换。但是，英国铁路行业正在经历乘客人数和货运量的显着增长，从而减少了进行维护的机会。鉴于这些问题，铁路排水系统的现代化被认为是提高铁路网络安全和容量的关键因素，并确保基础设施对不断变化的天气和气候事件的韧性。该项目着重于提供新颖且易于安装的铁路排水解决方案，这些解决方案利用轻巧且具有成本效益的“新材料”。 “新材料”包括最近开发的材料以及可以在排水系统中新应用的材料。该项目将考虑在此应用中使用的一系列材料，例如扩展的聚苯乙烯（EPS），它是一种轻巧且强大的材料，具有良好的耐化学性。该项目包括一系列实验测试，包括在全面的铁路轨道模型中对新材料排水系统进行的试验，以及使用诺丁汉岩土技术离心机的高级小规模物理建模。还将开发数值模型，以更好地了解排水系统中关键参数的影响。该项目的一个重要组成部分是开发工具，该工具将允许评估开发的新物质排水解决方案的全生命成本。这些工具有可能帮助铁路运营商做出与选择轨道和排水系统维护和维修解决方案有关的明智决定。还将开发高级工具，这将更好地了解铁路排水性能与其他铁路系统（包括其他基础设施资产和运营服务）之间的关系。该项目受益于铁路行业的专家参与，包括铁路领域的工程，建筑和技术服务的领先提供商以及为铁路行业提供一系列咨询服务的Aspin。该项目还将受益于从网络铁路（英国铁路基础设施的所有者）通过研究团队与网络铁路代表之间的良好联系。该项目促进了一种开发工程解决方案的多学科方法，并具有来自多个技术领域的专业知识，包括岩土技术，运输基础设施设计和绩效以及资产管理。该项目的成功完成将允许开发现代铁路排水解决方案，以结合新的轻量级，易于安装，易于安装和成本效益材料。作为该项目的一部分开发的生命周期成本评估工具将使铁路运营商能够就铁路维护和维修做出明智的决定，并确保铁路的最终用途获得最佳服务。
