| 摘 要： | 根据离开轨道中心15m处高速铁路的噪声暴露声级,通过引入地面衰减、屏障衰减和房屋建筑及树木的附加衰减参数,建立噪声理论分析模型。导出预测高速铁路牵引噪声、轮轨噪声和空气动力噪声的理论计算式。对秦沈客运专线铁路噪声进行了预测。经与实测数据进行对比,数据吻合良好。

| Abstract: | In light of sound exposure level for high-speed railway at 15 m from track center, a theoretical model for noise analysis is established by introducing ground attenuation, shielding attenuation and excess attenuation from buildings and trees. Then theoretical calculation formulas for predicting propulsion noise,wheel rail noise and aerodynamic noise from high-speed railway is deduced and the prediction of the railway noise of Qin-Shen dedicated passenger line are predicted. Good agreement between the predicted results and the measurements is obtained. |
