摘　　要：介绍隔声屏障声学原理及Cadna/A软件,以天津南1 000kV交流特高压变电站设计项目为例,采用Cadna/A软件对该变电站不同高度的隔声屏障降噪效果进行预测,将Cadna/A软件的预测结果与绕射损失理论公式计算结果进行比对,认为Cadna/A软件计算的插入损失比理论公式计算的插入损失稍高,在实际应用中,需要结合变电站实际检测数据,对Cadna/A仿真预测软件计算的插入损失进行修正。This paper describes the acoustic principle of sound barrier and the Cadna/A software,in the design project of Tianjin south 1 000 kV AC substation,different height noise barrier effect is predicted by Cadna/A software,the Cadna/A software prediction results were compared with the loss theoretical formula calculation results,that the Cadna/A software results are a slightly higher than the theoretical formula results,in the practical application,the Cadna/A simulation prediction software need to correct combined with the actual measurement data.
