| 中文摘要: |
| 城市轨道交通的快速发展在创造良好的经济、社会和环境效益的同时,也不可避免地给城市带来了振动和噪声问题。通过对噪声源进行分析,得出轮轨噪声是城市轨道交通的主要噪声源。因此,合理选择轨道结构的型式是最为有效的减振降噪措施。通过对各种轨道结构减振型式的分析比选,得出轨道减振设计中合理、有效的减振降噪措施。 |
| 英文摘要: |
| While the rapid development of urban rail transit creates well economic, social and environmental benefits, it brings along quite a few problems of noise and vibrations inevitably. According to the analysis of noise origin, we get the conclusion that wheel-rail noise plays the most important role in the field of noise origin of urban rail transit. Consequently, the selection of reasonable types of track structure is becoming the best measure to reduce noise and vibrations. By comparisons among various kinds of track structure, the suggestions are made on reasonable and effective measures for track vibration reduction designs. |
