摘要
本文对海南东环铁路海口城区的南海大道附近的敏感点列车开通的近期(2020年)和远期(2030年)的噪声进行预测;根据噪声暴露声级与等效声级的关系公式,对列车加密后南海大道距离轨道30m处的噪声进行预测,发现当小时列车数达到14车次时,其昼间等效声级将超过70dBA的标准,为城区段控制小时列车次数提供参考。
This paper predicts the noise in recent （2020） and long - term （ 2030 ） near the opening of the South Sea Avenue oI Haikou city of Hainan East Ring Railway; According to the noise exposure sound level and the relation formula of equivalent sound level, on the train after the encryption of the South Sea Avenue from orbit predict the noise of the 30m place, found that when the hour train number 14 trains, equivalent sound level of the day will be the standard of more than 70 dBA, provide reference for district section control hours train number.
