Quantitative Comparison Method of Choosing Protection Schemes of Highway Cut-Slope Based on Environment Protection

Using the basic economic principles and the methods of carbon tax, production cost, alternative engineering and market value, this treatise analyzed the value of slope protection reducing the soil erosion, the value of vegetation sequestrating carbon dioxide and releasing oxygen, the value of conserving the source of water, the value of restraining dusts, the value of sequestrating sulfur dioxide and the value of improving landscape. At the same time it put forward the methods how to estimate the benefits quantitatively and bulit the quantitative comparison method of choosing protection schemes of cut-slope. The conclusions of quantitative comparison method are clear. That could be helpful in slope protection decision-making when the conclusions of qualitative comparison are different from the quantitative comparison.
