ABSTRACT
The proper aesthetic disposal and landscape design of road sound barriers would well compensate the negative visual influences on the environment and improve road landscape environment effectively. Based on the analysis of the relationship between visual disturbance and landscape compensation, the spatial characteristics of road sound barriers were identified. The landscape design requirements of road sound barriers with different spatial form and different wall parts were all studied respectively in detail in consideration of the acoustic and non-acoustic functions of sound barriers. And the dynamic visual aesthetic features of road sound barrier were also determined from the perspectives of the relationship between speed and vision and the relationship between texture and material. The landscape compensation design methods of road sound barrier on the basis of visual aesthetic factors were proposed respectively from the five aspects of sequence and rhythm, spatial enclosure, visual orientation force, environmental compatibility and regional culture.
