A continuous increase in the worldwide demand for high-speed traffic, freight tonnage as well as of the train operating frequency is worsening the decay conditions of many railway infrastructures. This occurrence affects economy-related business as well as contributing to rising maintenance costs. It is known that a failure of a railway track may result in tremendous economic losses, legal liabilities, service interruptions and, eventually, fatalities. Parallel to this, requirements to maintain acceptable operational standards are very demanding. In addition to the above, a main issue nowadays in railway engineering is a general lack of funds to allow safety and comfort of the operations as well as a proper maintenance regime of the infrastructures. This is mostly the result of a traditional approach that, on average, tends to invest in high-priority costs, such as safety-related costs, compromising lower-priority interventions (e.g., quality and comfort of the operations). A solution to correct this trend can be moving from a reactive to a proactive action planning approach in order to limit more effectively the likelihood of progressive rail track decay. Within this context, this paper reports a review on the use of traditional and non-destructive testing (NDT) methods for the assessment and health monitoring of railway infrastructures. State-of-the-art research on a stand-alone use of NDT methods or a combination of them for quality control, inspection and maintenance tasks in this subject area is discussed.

铁路基础设施无损评估与健康监测

全球对高速交通、货运吨位以及列车运行频率的需求不断增加,正在加剧许多铁路基础设施的衰败状况。这种情况会影响与经济相关的业务,并导致维护成本上升。众所周知,铁路轨道的故障可能会导致巨大的经济损失、法律责任、服务中断,并最终导致死亡。与此同时,维持可接受的操作标准的要求也非常苛刻。除上述之外,如今铁路工程的一个主要问题是普遍缺乏资金来确保运营的安全性和舒适性以及基础设施的适当维护制度。这主要是传统方法的结果,平均而言,倾向于投资于高优先级成本,例如与安全相关的成本,从而损害较低优先级的干预措施(例如,操作的质量和舒适度)。纠正这一趋势的解决方案可以是从被动的行动规划方法转变为主动的行动规划方法,以便更有效地限制渐进式铁路轨道衰减的可能性。在此背景下,本文回顾了使用传统和无损检测 (NDT) 方法对铁路基础设施进行评估和健康监测的情况。讨论了单独使用 NDT 方法或将它们组合用于该主题领域的质量控制、检查和维护任务的最新研究。纠正这一趋势的解决方案可以是从被动的行动规划方法转变为主动的行动规划方法,以便更有效地限制渐进式铁路轨道衰减的可能性。在此背景下,本文回顾了使用传统和无损检测 (NDT) 方法对铁路基础设施进行评估和健康监测的情况。讨论了单独使用 NDT 方法或将它们组合用于该主题领域的质量控制、检查和维护任务的最新研究。纠正这一趋势的解决方案可以是从被动的行动规划方法转变为主动的行动规划方法,以便更有效地限制渐进式铁路轨道衰减的可能性。在此背景下,本文回顾了使用传统和无损检测 (NDT) 方法对铁路基础设施进行评估和健康监测的情况。讨论了单独使用 NDT 方法或将它们组合用于该主题领域的质量控制、检查和维护任务的最新研究。本文回顾了使用传统和无损检测 (NDT) 方法对铁路基础设施进行评估和健康监测的情况。讨论了单独使用 NDT 方法或将它们组合用于该主题领域的质量控制、检查和维护任务的最新研究。本文回顾了使用传统和无损检测 (NDT) 方法对铁路基础设施进行评估和健康监测的情况。讨论了单独使用 NDT 方法或将它们组合用于该主题领域的质量控制、检查和维护任务的最新研究。
