【摘要】 首先根据公交车的运行特性提出了公交车在各行驶阶段的噪声计算方法并采用能量叠加的方法建立了公交车站附近交通噪声预测模型。然后对广州市新港西路交通噪声的实测结果与模型计算结果进行了比较,验证了该预测模型的正确性。最后分析了公交车站附近交通噪声的影响因素,通过对公交车站附近的交通噪声和远离公交车站的交通噪声的比较,得到公交车站附近交通噪声明显增大的结论。更多还原

【Abstract】 Firstly,a method of calculation for bus noise in each moving stage was brought up according to the characteristic of the bus motion,and a traffic noise forecasting model for the place near a bus stop was deduced by using the energy superposition method.Then the validity of this model was verified by comparing the measured traffic noise level at Xingangxi Road in Guangzhou City with the forecasted traffic noise level.Finally,the influence factors of traffic noise near a bus stop were analyzed.It can be concluded that the Traffic noise level near a bus stop will have a significant increases compare with the homologous place where the bus stop is not exist.更多还原
