The Research Of Plant Protection On Red Clay Slope In Subtropical Rainy Area

This Paper is relying on the protection and reinforcement technology research of soil slope in subtropical rain-fed areas. On the basis of comprehensive research on the SiMao~JiangCheng road,study on the classification of soil slope in subtropical rainy region, analysis of influence factors and failure characteristics of slope stability, determination of the self-regulation and rational slope rate of soil slope, evaluation of selection and applicability of slope protection and reinforcement technology.Relying on the Si-Jiang road, through on-site investigation、information collection、experimental study、theoretical analyses、and numerical simulation, On the base of existing research, the achievement as following:(1)Proposed classification method of soil slope,given the influencing factors of soil slope stability, and Classification of soil slope failure in subtropical rainy region.(2)According to the research of mechanical Parameters and its influencing factors on red clay soil slope, the soil slope vegetation protection and strengthening mechanism in subtropical rain-fed areas is depth and systematic studied. It is given that where the slope protection type in sub-tropical rainy regions is applicable with the existing slope reinforcement and protection status.(3) It gives out the slope stability rate of Cutting Slope on the basis of red clay slope stability analysis along Si-Jiang road.(4)On the base of slope research and slope stability analysis on the Si-Jiang road, put forward reasonable excavation slope rate in the subtropical rainy regions.(5)On the base of slope reinforcement and protection research, given type and application of slope protection in subtropical rainy regions.(6)In different conditions, this Paper analyzes zhe reinforcing effect of herbaceous vegetation on the soil slope. In primary and secondary slope, the slope stability cofficient incresed under the action of herbaceous vegetation.(7)On the basis of analyzing the reinforcement effects form single and combined root of woody plant on soil slope, it is find that the longer the roots, the better the reinforcing effect. According to to the analysis of different root implantation angle,the optimum angle is inferred.
