Slipped expansion of land area road slope collapse , collapse the shoulders and shallow landslide is the engineering difficult to cure \Start of the project from the expansion the land area highway slope failure in the form and protective Survey , analyzed the causes and forms of expansive soil slope failure , comprehensive waterproofing and drainage engineering protection of plant protection protective method of expansive soils slope protection. Analysis of plant the slope protection role , function and mechanism of plant species and plant combinations for slope protection mode screening the proposed the herbaceous shrub combination of slope vegetation Quick shrubs . Design of integrated drainage protection , protective mode selection research, the expansive soil slope with the top of the hill to the \the face set surface drains , the foot of the slope set \Moisture Sensor observations of soil erosion on the water content of the slope of relying on engineering , the results of a comprehensive anti - drainage works protection and plant protection research applied to Yunnan An Chu , Yan Ping Expressway expansive soil in highway slope based on the project , slope failure , plant growth conditions , a comprehensive testing and comparative analysis of the results showed that the comprehensive protection measures proposed full use of the advantages of the engineering and plant protection , plant transpiration and coverage , effectively inhibit the slope soil water content is rapidly changing , waterproofing and drainage measures and plant roots extend into soil stability , reinforcing the slope , greening and landscaping . Provide technical support and guarantee for expansive soil slope protection and environmental protection .
