摘　　要：基于山地城市特殊城市形态,对多层次复合铁路建设模式下的噪声特性研究尚不多见。通过对山地城市多层次复合铁路噪声进行实地调研、现场试验、数据处理、噪声特性分析,研究了山地城市多层次复合铁路列车不同运行工况下的噪声特性,得到了不同车型列车通行、鸣笛通行、同时通行以及昼夜间背景噪声特性变化情况,可为山地城市多层次复合铁路噪声声源特性及其相关计算分析提供基础数据参考。For the special landscape of mountainous cities,study on noise characteristics under the multi-level composite railway construction mode is still rare.Through field investigation,on-site experiment,data collection and processing,and noise characteristics analysis,the noise characteristics of the multi-level composite railway in mountain cities under different operating conditions were studied,deriving the changes in noise characteristics under different conditions of trains running,whistling while running,simultaneously running,and running at day and night,which can provide basic data reference for the noise source characteristics of the multi-level composite railway in mountainous cities and relevant calculations and analyses.
