Study On Ecological Slope Protection Technology In Loess Area

Many of the civil engineering works built in Loess Area may produce slopes that can not rely on nature to restore vegetation.Because the loess has high content of CaCO3,vertical joint development and encountered water strength decreases,the slope prone to collapse and landslide.These disasters had affected agricultural production and people's life safety,and more and more attention has been paid to the management of slope.The paper analyzed the characteristics of the Loess in Guanzhong,the type and characteristics of the slope failure.The paper is research on the ecological slope protection mechanism and its influence on slope stability.The following results were obtained:(1)According to the principles of slope selection and plant community allocation,while considering the geological climatic,environmental conditions and other natural conditions,configured plant communities suitable for Guanzhong loess tableland area.(2)Based on the characteristics of Loess slope,the slope stability evaluation system of five major factor layers and twelve evaluation indexes were constructed.(3)For specific engineering examples,the slope stability evaluation system determined by this paper was used to solve the weight of each index with YAHP software.Evaluation of the specific actual slope and the results show that it was in an unsafe state,so it was necessary to deal with the slope.(4)The slop who was used of ecological slope protection means,though using the GeoStudio software to analyze the seepage and steady state of the ecological slope before the rainfall,between the rainfall and after the rainfall.The results show that the treated slope meets the actual and standard requirements under various conditions.Ecological slope protection can prevent soil erosion,weaken splash erosion,improve environment,restore vegetation,reduce noise,clean air and regulate microclimate.The promotion and application of ecological slope protection technology can promote the coordinated development of engineering construction and ecological construction.
