LOCORPS: Lowering the Costs of Railways using Preformed Systems

英国和世界各地都在开发速度和距离不断增加的高铁线路，但前期资本支出可能会成为客户和公众眼中的一个主要制约因素。如果实体建设的初始成本、建设持续时间和土地占用能够减少，这些线路的成本就可以降低。如果该行业转向一种新的堤防替换系统，所有这三种堤防成本都有可能降低。此外，路基置换系统可以更好地控制所含材料的动力特性，从而显着改善轨道结构的性能。然而，这种技术需要进行重大的性能评估，并制定适当的设计指南，英国工业才能在项目中合理地实施它。因此，该项目旨在评估和编制两种新型路基替换系统的设计指南，作为潜在地降低建设新的高速铁路线(特别是在城市环境中)的成本并改善整体轨道行为从而改善乘客体验的一种手段。

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.
