摘　　要：城市轨道交通地下线风亭噪声的预测和评价与其源强的选取直接相关,目前风亭噪声源强的选取主要采用类比监测法。本文探讨了风亭噪声源强类比需要考虑的影响因素,包括风机类型和型号、消声器类型和规格以及风亭结构,同时也提出了一些容易被忽略但却会对风亭噪声源强类比产生影响的因素,包括设备老化、监测工况、消声器的安装和施工是否规范、消声器安装方式是否一致,为环评工作者提供参考。The prediction and evaluation of wind pavilion noise in urban rail transit are directly related to the selection of its source intensity.Currently,the selection of wind pavilion noise source intensity mainly adopts on measuring in similar sites.This article explores the influencing factors that need to be considered in the analogy of wind pavilion noise source intensity,including fan type and model,muffler type and specification,and wind pavilion structure.At the same time,some easily overlooked factors that can affect the analogy of wind pavilion noise source intensity are also proposed,including equipment aging,monitoring conditions,whether the installation and construction of mufflers are standardized,and whether the installation method of mufflers is consistent.
