LOCORPS: Lowering the Costs of Railways using Preformed Systems

在英国和世界范围内，高速铁路的发展速度和距离都在不断提高，但前期资本支出可能成为客户和公众眼中的主要抑制因素。如果能够减少实际建设的初始成本、建设时间和占用的土地，这些线路的成本降低是可以实现的。如果该行业转向一种新的堤防更换系统，这三种成本都有可能降低。此外，路基更换系统可以更好地控制所含材料的动力特性，从而显著改善轨道结构的性能。然而，在英国工业能够合理地在项目中实施这种技术之前，这种技术需要进行重要的性能评估和制定适当的设计指导。因此，本项目旨在评估和制定两种新型路堤更换系统的设计指南，以潜在地降低建设新高速铁路线的成本（特别是在城市环境中），并改善整体轨道性能，从而改善乘客体验。

High-speed rail lines, at ever increasing speeds and distances, are in development both in the UK and world-wide, but up-front capital expenditure can potentially be a major inhibiting factor both to the client and also in the eyes of the public. Cost reductions for these lines could be achievable if the initial costs of the physical construction, the duration of construction and the land take could be reduced. All three of these costs can potentially be reduced for embankments if the industry were to move towards a novel embankment replacement system. In addition embankment replacement systems could significantly improve the performance of the track structure as the dynamic properties of the contained material can be better controlled. However, such technology requires significant performance evaluation and the development of appropriate design guidance before UK industry can justifiably implement it in a project. This project therefore aims to evaluate and produce design guidance for two novel embankment replacement systems as a means to potentially reduce the cost of constructing new high-speed railway lines (particularly in urban environments) and improve the overall track behaviour and hence passenger experience.
