【摘要】 为提高铁路噪声的预测与评价水平,提出了基于GIS的铁路噪声预测与评价方法．将GIS与铁路噪声预测模型进行集成,通过选取预测铁路,输入相关参数,调用预测函数和绘图函数进行噪声计算和绘制等声级线,可以根据噪声值表和等声级线分布图进行铁路噪声的影响分析并制订相应对策．更多还原

【Abstract】 In order to improve railway noise prediction and estimation,a railway noise prediction and estima- tion method based on GIS is advanced.It integrates GIS and railway noise prediction model.Noise data calcu- lation and noise contour drawing is carried out through selecting railways,inputting correlative parameters, transferring prediction function and drawing function.The user may analyse noise effect and take correspond- ing countermeasure.更多还原
