| Abstract: | The road in pastoral area is a special kind of highway, which is ready to suffer from snow hazard and sand hazard. Based on the analysis of the speed of wind blowing across The Snow Protection Facilities And Sand control Facilities with FEM, the speed field of Snow-bearing wind and Sand-bearing wind was simulated, then the reasonable position, height and modality of the protection facilities were proposed. |
