摘　　要：城市轨道交通在给城乡居民带来出行便利的同时,其产生的交通噪声扰民问题不容忽视;以北方某城市轨道交通工程为例,通过实测分析评价轨道交通地面高架段噪声对沿线高层住宅小区影响,论证若干种噪声控制措施的经济技术可行性;除通过设置声屏障等常规传播途径削减噪声、通过设置隔声窗等对受声点采取被动防护措施外,调整特殊时段、路段列车运行参数也不失为一种有效主动控制措施,可降低源头噪声,有关结论可为同类轨道交通项目噪声防治及运营管理提供借鉴。While urban rail transit becomes convenience to urban and rural residents,the disturbance of its traffic noise to the residents is indispensable.With a rail transit project in a northern city as an example,the ground elevated section of rail transit is used to evaluate the noise impact of rail transit on high-rise residential communities along the line.The economic and technical feasibility of several noise control technical measures is discussed.It is shown that installation of sound barriers and some other conventional means and passive protection of sound points such as sound insulation windows can effectively reduce the noise,while the adjustment of train operating parameters for special periods and sections can also be the effective active control measures to reduce the source noise,This study provides a reference for the noise prevention and operation management of similar rail transit projects.
