客运索道噪声特性与控制分析

Noise Characteristics and Control Analysis of Passenger Ropeway

为探究客运索道噪声污染，基于福建省福清石竹山、泉州仙公山、三明麒麟山及广东深圳大侠谷4处客运索道噪声实测数据进行误差分析、模型处理、均值统计、回归拟合、环境评价．结果表明：客运索道噪声污染源主要为驱动机；驱动站等效声级为70～90dB，暴露噪声处于吵闹水平，噪声环境达重度污染；非驱动站等效声级为50～60dB，暴露噪声水平一般，噪声环境也受到不同程度污染；驱动站声场均匀，非驱动站声级波动明显，但两站房噪声分布较稳定；驱动与非驱动站声级分布线性与非线性回归拟合优度均近于0，拟合效果不好，声级分布无规律可循．以综合防治为目标，从优化驱动制造安装、合理进行休息室选址、规范管理等方面提出客运索道降噪控制措施．

To explore the noise pollution of passenger ropeway, this study measured the noise level of Shizhu mountain in Fuqing, Xiangong Mountain in Quanzhou, and Qilin Mountain in Sanming in Fujian Province, and Daxiagu in Shenzhen based on the error analysis, model processing, mean statistics, regression fitting and environmental assessment of measured noise data. The results showed that the main noise pollution source was driving machine ; the equivalent noise level of drive station was 70 ~ 90 dB ; noise exposure level was noisy ; noise environment pollution approached to severe level. While, the equivalent noise level of non-drive station is 50 ~ 60 dB;noise exposure level was general, but the noise environment pollution was also subject to different degrees. The noise field of drive station was evenly distributed, however, the noise level fluctuation of non-drive station was obvious. The overall noise distribution of two stations kept stable, but the fitting optimal degree of noise distribution in both stations by linear and nonlinear regression tended to zero. Meanwhile, setting comprehensive prevention and control as the goal, specific noise control measures of passenger ropeway were proposed by optimizing drive manufacturing and installation, rationalizing the lounge location, standardizing the management etc.
