Protection Technology Of River Bends And Experimental Study On Its Effect Of Soil Erosion Control

To study the mechanism of anti erosion of river bend protection technology and research on the factors affecting erosion of slope protection, It selects typical river bend of the Shandong Haihe River Basin Tuhai River ,and experiments on the ecological slope protection impact. It uses four different types of ecological slope protections as the experimental object to analyze the test data and compare the experimental phenomena. Experimental results show that: In different flow conditions, the slope erosion and scour seem basically consistent. Individually stake slope protection effect is poor. Stone-cage slope protection, spur-dike slope protection and the stake and grass protection firm the bottom of the slope obviously. The soil loss of spur-dike slope is the lowest, flow velocity between spur dikes decreases significantly and soil reinforcement increases more than 70% compared with spur-dike slope. The experiment provides technical support for Tuhai River bend slopes.
