On the Landscape Evaluation and the Construction Cost of Roadside Slope Protection

This study examines the relation between respected evaluation of landscape and construction costs of slope protection works. The nine experts tested 100 leaves of photographs by two standards. The result of experiment was analyzed by the quantification theory method. The use material, the surface design, the lower part design, and the combination of design types are effective. As the material of retaining wall, though the cost of construction is high, stone is evaluated better than concrete blocks. The profitable method was no handling and revegetation. Mortar sprayed and concrete crib work took disadvantage.
