Construction projects are mostly located in valleys, steep slopes and other terrains, with narrow sites and inconvenient transportation, large-scale construction machinery is difficult, and the material supply cost is high. The use of slope reduction in high fill sections requires occupying a lot of land outside the road sideline. For example, if the fill height is 10m, the slope reduction requires an area of ​​15m, and if it exceeds 6m, it is necessary to increase the width of the staggered graded slope reduction by 2m.
