| 摘 要： | 在对我国高速铁路环境振动实测的基础上，分析了我国高速铁路环境振动特性。实测分析结果表明：对于350km／h客运专线，高速动车组运行时铁路环境振动主频出现在40Hz左右；对于250km／h客运专线，高速动车组运行时铁路环境振动主频出现在25Hz左右；货物列车运行所产生的铁路环境振动，其主频大多出现在12．5Hz左右。地面环境振动传播规律为近场范围内距线路距离加倍，环境振动衰减2～3dB。列车引起的地面振动随车速的提高而增大，与日本新干线的桥梁及其周围地面的振动进行的测试结果基本一致。 |

| Abstract: | On the foundation to the environmental vibration of High-speed Railroad through field measuring,analyzed the environmental vibration characteristic of high-speed railway.The result indicated that: Regarding the 350 km/h high-speed railroad,when CRH runs,the basic frequency of the environmental vibration mostly appears about 40Hz.Regarding the 250 km/h high-speed railroad,when CRH runs,the basic frequency of the environmental vibration mostly appears about 25Hz;when the freight train runs,the basic frequency... |
