摘要
上海市轨道交通明珠线在国内首次采用1:1实况模拟形式进行了长度为250m的声屏障试验工程,按不同距离、高度设置13个测点,在各测点上做了8次不同材质结构的声屏障效果测试。实况模拟获得的大量数据资料和结论,对降低轨道交通的列车运行噪声有着积极的现实意义。
In order to get the correct Insertion Loss(IL)of sound barrier of Shanghai track-traffic, first time in China, used a real measurement model (ratel:1), under diffenent distances and height to set 13 measuring points, at each point eight times of effect of sound barrier on different materials have been measured. Actual simulation obtained a lot of useful data which are significant and could be used for reducing noise pollution of track-traffic.
