| description | In order to mitigate the ecological impact of traditional binders (such as silicate cement) used for slope reinforcement, the present study employed xanthan gum (XG), guar gum (GG), and their hybrid gum (HG) to replace traditional binder materials for preparing eco-friendly slope protection substrates, and conducts vegetation trials. It analyses the effects of different types and dosages of gums on plant germination rates and projected coverage, determining the optimal dosage for each gum. Based on the optimal proportions, rainfall erosion tests were conducted on slope models to analyze the erosion resistance of various gum slope protection schemes compared to bare soil slopes, alongside variations in substrate moisture content and slope damage
characteristics. The results indicate that the vegetation performance of XG substrate increases with higher dosages, while the performance of GG and HG first increases and then decreases with higher dosages. The optimal improvements in vegetation performance are observed at 2% XG, 1.5% GG, and 1% HG. A rainfall erosion test with an intensity of 1 mm/min for one hour was conducted on slope models of “XG-ryegrass”,
“GG-ryegrass”, “HG-ryegrass” and “Clay”. Compared to “Clay”, the soil loss for “XG-ryegrass”, “GG-ryegrass”, and “HG-ryegrass” is decreased by 65.25%, 71.55%, and 66.17%; the slope erosion is decreased by 66.9%, 70.4%, and 68.71%; the slope failure levels are classified as Grade III, superior to the Grade VII of “Clay”. These three combined soil stabilization methods exhibit excellent rainfall erosion resistance and slope protection effects. |
