前言地铁列车运行时,由于车轮与钢轨互相撞击而产生运行噪声,可区分为:通过空气传播的,简称为空气噪声;通过固体振动传播的振动噪声,简称为固体声。空气噪声对站台上和列车内的乘客带来影响,并通过通风井传播到地面风亭附近居民区成为污染声源。固体声对地铁沿线居民区造成不同程度的影响,特别是一些对噪声要求较高的建筑物更是不容忽视的。国外地铁运营中对运行噪声的危害性予以充分重视,进行工程实测或模型试验研究,采取各种技术措施,收到一定效果。现将如
Preface The subway train running, due to wheel and rail collide with each other to produce operating noise, can be divided into: airborne, referred to as air noise; vibration noise transmitted by solid vibration, referred to as solid sound. Airborne noise affects the passengers on the platform and in the train, and spreads through the ventilation shafts to the residential areas near the surface wind kiosk as sources of pollution. Solid sound has different degrees of impact on the residential areas along the MTR. In particular, some buildings that require high noise can not be ignored. Foreign operation of the subway operation of the dangers of noise to give full attention to the engineering test or model test research, to take various technical measures, to a certain extent. Now as
