Highway Sound Barrier Selection And Evaluation

With the development of highway transportation and urban road construction, the traffic noise pollution becomes very important problem. Sound barrier, a effective measure of controlling noise, will have great perspective.According to form,structure and stuff, the author ranges and induces road sound barrier systematically, describes their sound properties and mechanical properties, draws all kinds of structural graphic of sound barrier. On the base of sound barrier's survey of expert assessment system, the standard and method of expert assessment is putforward, making comprehensive rating to sound barrier effectively. Finally there is a engineering example involving the studied content. Thus has practical significance to the designing of sound barrier in China.
