Analysis of Influence of Geotextiles on Slope Erosion Under Rainfall Conditions
Natural factors and human activities have adverse effects on the stability of the bank slope of the reservoir,and lead to the landslide disaster of the bank slope in serious cases.Therefore,based on the reservoir slope project,this paper designs the reservoir bank slope test model under rainfall conditions.By comparing the results of rainfall collection rate,sediment amount and sediment content under bare slope,geomembrane and geotextile schemes,a reasonable slope protection scheme is determined.The test results under different geotextile spacing and width are compared systematically,and the geotextile parameters are optimized.The results show that the geomembrane slope protection scheme has a better effect on the improvement of silt and sediment content than the geomembrane slope protection scheme.The larger the geotextile width and the smaller the interval,the most obvious erosion effect of rainfall on slope is weakened.The slope protection scheme with geotextile width of 5cm and interval of 0.2m is the best.The research methods and contents of this paper can provide guidance for similar projects.
