摘要
根据《京沪高速铁路暂行规定》确定的原则推导了声屏障附加长度的理论计算方法,采用菲涅耳数-前川表法估算了不同距离、不同高度声屏障的降噪效果,并通过现场实测结果提出了声屏障设计中应采用的控制范围。
extrapolate the algorithm of additional extent of acoustic baffle by following Jing-Hu High-speed Railway Tentative Provision, approximating the varied denoise effect of acoustic baffle with different distance and height, propose preferred controlled range that shall be taken in acoustic baffle design through field survey.
