Research On Anti-erosion Effect Of Ecological Slope Protection Of Inland Waterway

Based on the status and problems of inland waterway revetment in Anhuiprovince, the paper puts forward that inland waterways should implementecological slope protection technology in Anhui province. The paper lists thecommon ecological slope protection types of inland waterways and commonecological slope protection plants at home and abroad through the literature reviewand the accumulation of experience in engineering application. Combined with thenatural conditions of Anhui province, inland waterway situations, etc., consideringthe maneuverability of the tests, four kinds of revetment types, which are plantinggrass slope protection, prefabricated spherical ecological concrete slope protection,square grid concrete and grass slope protection and riprapping grass slopeprotection, and three types of slope protection plants, which are cynodon dactylon,vetiver and dwarf lilyturf, are screened out. It shows that the prefabricatedspherical ecological concrete slope protection and the square grid concrete andgrass slope protection have a better anti-erosion effect, according to the results ofstudy on the anti-erosion effect of the four selected ecological slope protectiontypes. It concludes that cynodon dactylon is the most suitable plant for inlandwaterway revetment in Anhui Province from two experiments for the selectedplants, which are turf erosion resistance experiment and runoff scour simulationexperiment.In order to choose the most suitable ecological slope protection from theselected four kinds of revetment types, comprehensive evaluation is adopted.Synthetic evaluation index system of ecological slope protection of inlandwaterway is established, the corresponding evaluation content is expounded, andthe evaluation standard is made. Analytic hierarchy process (AHP) is taken toevaluate the four types of slope protection. According to the results ofcomprehensive evaluation, four types of revetment type evaluation results are"good". Based on the evaluation score, it is suggested that inland waterway inAnhui province prefers the square grid concrete and grass slope protection,followed by the prefabricated spherical ecological concrete slope protection.
