Abstract


China 's large-scale road building, it will have an adverse impact to the acoustic environment along the road . Highway Environmental Protection Acceptance Check is an important part of the environmental management of highway construction projects , the completion of the practical problems arising in the investigation of environmental protection acceptance , according to Fujian Province, Funing Expressway attenuation cross-section of the acoustic environment acceptance of the completion of the highway construction project Select and sound environmental protection acceptance reporting methods were studied . Noise attenuation representative cross-section should be selected in the open , the height difference is smaller , the location of vegetation . The value to be a true reflection of the monitoring road noise size , spread , attenuation attenuation cross section monitoring . In the cross-section monitoring , the monitoring points are generally from 1.2 meters high above the ground , the barrier function of the monitoring points will be away from the road near the embankment . This paper analyzes the scope of the embankment of the barrier function , the proposed monitoring sites in the acoustic shadow formula according to district or sound judgment and correction method of monitoring sites for monitoring the value of the acoustic shadow zone . Funing Expressway bilateral acoustic barrier noise reduction effect of bad analysis , mainly bilateral acoustic barrier parallel toward the sound source on one side did not install sound-absorbing device diffraction sonic reduce the insertion loss of the sound barrier ; and the amount of attenuation of the sound barrier diffraction is calculated based on acoustic principles , practical remedies . Finally, an instance , the establishment of a highway construction projects completed in sound environmental protection investigation procedures , analysis of the purpose of the investigation , in principle , based on survey content and implementation of standards , research reporting , the report includes the following : Overview ; scope of the investigation methods the determining factor ; along the highway sound environmental protection investigation ; acoustic environmental quality evaluation and sound environmental protection status of acoustic environmental quality monitoring and public participation in the survey ; sound environmental monitoring results ; findings .
