| 中文摘要: |
| 重载铁路运输的快速发展提高了铁路的运输能力和经济效益，但列车轴重提高和编组增加使既有铁路桥梁病害日益加剧。现有的铁路桥梁劣化评定标准中的检查内容、检查方法和等级评定标准等存在着一定的局限性，按照既有规范进行劣化等级评定不能准确反映重载桥梁结构的实际技术状况,因此，迫切需要进行重载铁路桥梁标准化劣化评定技术的研究。本文主要针对朔黄铁路桥梁劣化现状，结合既有规范对铁路桥梁劣化评定进行研究，并根据研究结果对朔黄铁路桥梁进行了劣化评定，以此形成一套重载铁路桥梁标准化劣化评定技术规程。 |

| The rapid development of the transportation of Heavy duty Railways improve the transport capacity of the railway and economic benefits, but the train axle load and marshalling increase railway bridge disease aggravation. The existing railway bridge deterioration evaluation standard check the contents, norms in the deterioration of inspection method and evaluation standard, there are some limitations, in accordance with the existing norms of deterioration rating does not accurately reflect the actual technical condition of heavy duty of bridge structure. Therefore, we need to study the bridge of heavy duty railway standardization deterioration evaluation technology, This article in view of the present situation of Shuo Huang railway bridge deterioration, combined with the deterioration of the existing norms of railway bridges assessment study and based on the findings of Shuo Huang railway bridges were assessed deterioration, thus forming a set of heavy haul railway bridge deterioration standardized assessment of technical regulations. |
