| Eco-Protection Technology is a kind of engineering technology rising with construction of Expressway in the whole world. Different from the traditional engineering protection technology, Eco-Protection Technology combine traditional engineering protection and vegetation protection properly. It utilize deep-stabilizing slopes of engineering protection and super- stabilizing and biological function of vegetation protection to achieve the purpose of consideration between engineering construction and environmental protection, fully, People pay attention to environmental protection and life quality more and more nowadays, Using Eco-Protection Technology becomes a kind of trend in slope protection of highway, it also represent the developing direction of slope protection.At present research of Eco-Protection Technology concentrate on construction craft and research on water and soil conservation mainly, neglect plant engineering mechanics behavior of root system protection research combined together with plant protection and engineering protection. On the basis of study the available relevant materials about the Eco-Protection theory and application, firstly, it summarizes the mechanical action, Hydrology effect, Ecological effect and landscape effect of Eco-protection by numberial theories and ways. Secondly, the paper states technology of vegetation construction from the selecting seed and dispose and the planting. Thirdly, the paper concludes the ways of Eco-Protection model, analyzes its specialties and applied situation, gives the opinion of setting up Eco-Protection system and comprehensive protection. Lastly the paper based on the study results of the Scientific and Technological Project of western region , The Subject on Study and Application the Technology of Slope Protection and Ecological Restoration along the expressway from Hu County to Yang County Shan'xi Province, quote practical application example to prove this system can solve actual expressway slope protection problem. |
