摘 要:近年来,由于高原机场数目和航班运输量持续增长,导致高原机场航空噪声问题进一步加剧。为了科学有效地评估高原机场噪声对周围环境的影响,本文基于高原机场特定环境条件与标准大气条件差异导致的噪声数据环境修正值建立适用于高原机场的离场航线噪声计算模型。同时,结合高原机场噪声数据及离场航线剖面信息建立离场航线周围噪声的空间分布。实验结果表明,基于高原机场环境修正后的噪声值及影响面积相较于修正前有所减少,且根据噪声三维空间模型可以确定高原机场离场航线对地面产生70 dB及以上声压级的航线高度区间在0~2 000 m之间。该研究有助于高原机场离场航线噪声的计算,为离场航线优化研究提供支持。In recent years,the continuous growth of plateau airport and flight transportation volume has led to further aggravation of aviation noise problems at plateau airport.In order to scientifically and effectively assess the impact of plateau airport noise on the surrounding environment,a noise calculation model of departure route suitable for plateau airport is established based on the environmental correction value of noise data caused by the difference between specific environmental conditions and standard atmospheric conditions at plateau airport.At the same time,combined with the noise data at plateau airport and profile information of departure route,the spatial distribution of noise around the departure route is established.The experimental results show that the noise value and affected area after the correction based on the plateau airport environment have decreased compared with those before the correction,and according to the three-dimensional spatial model of noise,it can be determined that the altitude range of the plateau airport departure routes that generate a sound pressure level of 70 dB or above on the ground is between 0 m and 2000 m.This study contributes to the noise calculation of departure route at plateau airport and provides support for departure route optimization studies.
