公路声屏障现状分析与实际插入损失验证

Current Situation Analysis and Actual Insertion Loss Verification of Highway Sound Barrier

本文针对天津市公路声屏障设置现状以及插入损失理论计算与实际监测结果分析,提出实际插入损失预测模型,并通过工程验证,得出天津市公路声屏障的插入损失预测数值与监测值相差在3 dB(A)以内,预测效果较好,可为后续公路声屏障设计提供借鉴意义。

According to the current situation of highway sound barrier setting in Tianjin and the analysis of insertion loss theoretical calculation and actual monitoring results, the actual insertion loss prediction model is proposed. Through engineering verification, it is concluded that the difference between the insertion loss prediction value and the monitoring value of highway sound barrier in Tianjin is less than 3 dB(A),and the prediction effect is good,which can provide reference for subsequent highway sound barrier design.
