As an auxiliary facility of highway, the shielding effect of sound barrier directly affects the physical and mental health of residents along the highway. In this paper, the overall structural form and screen material of common highway sound barriers are classified and compared with their performance. Taking the typical bridge-type sound barrier structure in Nanping City, Fujian Province as an example, the mechanical properties are checked and analyzed, and finally the design thinking is carried out from the aspects of structure, landscape and material selection. |
