摘要
为了研究小湾水电站高坝坝身泄洪噪声的影响范围以及各生产主要区域的噪声分布情况,首次开展了较系统的泄洪噪声原型观测工作。利用AR844在线式数字噪声计测量各观测工况噪声值,对比泄洪前后噪声分贝值,分析、总结噪声的主要影响、衰减规律,为小湾水电站运行管理人员的职业健康提供相关资料,以达到验证设计及趋利避害的目的。成果表明,离坝址越远,噪声的衰减越明显,泄洪噪声最大影响范围在坝下游约1.3km左右。
In order to study the impact of dam body discharge noise and the noise distribution in each major production area of Xiaowan hydropower station, a systematic archetypal observation work on flood discharge noise is carried out for the first time. Using the AR844 online digital noise meter to measure the noise values in each observation condition, compare the noise decibel value before and after the flood discharging, analyze and summarize the main influence and attenuation law of the noise, and provide relevant information for the occupational health of the operation manager of Xiaowan hydropower station, so as to achieve the purpose of verifying the design and avoiding the harm. The results show that the farther away from the dam site, the more obvious the attenuation of the noise, the maximum impact of flood discharge noise reaches about 1.3 km downstream of the dam.
