| 摘 要： | 中国正在大力发展城际高速铁路运输,而在线路中有隧道时,列车进出隧道所产生的微压波问题已经成为限制高速铁路安全、环保、健康发展的障碍.大量研究表明:隧道出口的微压波强度与压缩波的压力梯度成正比,可以通过分析压缩波的压力梯度变化来评价降低微压波的效果.采用模型试验方法,对缓冲设施、减压竖井降低压缩波峰值和压力梯度峰值的效果进行了测试分析.实验结果表明:减压竖井降低首波压力峰值、压力梯度峰值效果明显;洞口缓冲设施降低首波压力峰值的效果不明显,降低压力梯度峰值效果明显,并且降低压力梯度的效果与速度相关.

| Abstract: | In China,high-speed railway transmission between cities is being developed with much effort.On the line with tunnel the micro-compression wave created when train passing through tunnel has become a serious problem hindering high-speed railway transmission development in safety,healthy and without pollution.Large numbers of researches showed that the strength of micro-compression wave is in proportion to the pressure grade of compression wave.By analyzing the pressure grade of compression wave,the effect of ... |
