Abstract

The structural performance of derailment containment provision (DCP) was investigated using a grid steel frame. The DCP which was installed within the gauge of a track was capable of resisting the impact loading in the case of derailed wheels. It was also possible to control the excessive lateral movement of the derailed train. In this study, the structural performance of DCP with a post-installed anchor to a railway concrete sleeper was evaluated. For this purpose, a total of nine specimens were manufactured and static tests were conducted to investigate the structural performance. Furthermore, the shear resistance of the connecting anchor was also evaluated using grid steel frame specimens. The initial test indicated that the developed DCP for railway using grid steel frames had sufficient load-carrying capacity and performance equivalent to about 150% of the design load. The developed DCP also demonstrated sufficient load-carrying capacity up to about 140% of the designed load in combination tests that simulated conceivable boundary conditions. As analytical results, the overall DCP behavior for the specimen railway that utilized grid steel frames was appropriately tracked, and detailed information was presented.

使用网格钢架的铁路脱轨防护装置的结构性能评估

摘要使用网格钢架研究了脱轨防护装置（DCP）的结构性能。安装在轨道轨距内的 DCP 能够抵抗车轮脱轨时的冲击载荷。它还能控制脱轨列车的过度横向移动。在这项研究中，对在铁路混凝土枕木上安装后置锚的 DCP 的结构性能进行了评估。为此，共制作了九个试样，并进行了静态测试，以研究其结构性能。此外，还使用网格钢架试样对连接锚的抗剪性进行了评估。初步测试表明，为使用网格钢框架的铁路开发的 DCP 具有足够的承载能力和性能，相当于设计荷载的 150%。在模拟可想象边界条件的组合试验中，所开发的 DCP 也显示出足够的承载能力，最高可达设计荷载的 140%。作为分析结果，对使用网格钢架的试样铁路的整体 DCP 行为进行了适当跟踪，并提供了详细信息。
