深圳市某高速公路桩基础施工噪声影响研究

Characterizing the Noise Impact of Pile Foundation Construction on an Expressway in Shenzhen

大规模的城市建设与更新活动引发了一系列的城市环境问题,其中建设施工产生的噪音问题尤为突出。文章采用HT-8352型专业声级计实地监测、EIAN软件模拟和问卷调查相结合的方式,以深圳市某高速公路桩基础工程为例,对建设施工阶段噪声污染问题进行了分析。结果表明,一般需要距离施工过程噪声源超过160 m才能达标场界噪音控制标准。此外,通过工地周边居民受噪音影响情况调查发现,100%的受访者都表示受到了建筑施工噪声的影响,且影响程度较为严重,受访者最直接的防燥措施是考虑施工过程的"外出回避",最后,提出了建筑施工过程噪声污染控制对策和建议。

Large-scale urban construction and renewal activities led to a series of urban environmental issues,noise problems is particularly prominent.A survey on measuring,EIAN modeling and investigating the noise of pile foundation construction on an expressway in Shenzhen was conducted.The result shows that almost all the residents investigated are influenced by the construction noise.Noise conditions and rules in vertical and horizontal directions are analyzed and the noise level of monitoring sites is not qualified 160 m away from noise source,and the closer to the noise source,modeling values more near measured values.The countermeasures and suggestions are put forward,which could provide the references for prevention and control of the construction noise of expressway.
