摘　　要：为有效治理我国流域河岸边坡水土流失问题,依托山东省临邑县水利工程,室内设置不同土钉间距和坡度条件下的水土流失模型试验,深入研究土钉护坡技术在河岸水土保持与边坡治理中工作中的应用。研究发现:土钉护坡技术在河岸水土流失治理中具有高度可行性,有土钉护坡条件下的总土壤流失量较无土钉条件下减少82.67%。随着坡度的增大,边坡的土壤流失量均呈现出逐渐增加的变化趋势。随着坡角的增大,最大土壤流失量分别相对升高13.46%、34.61%及61.53%。在相同坡角条件下,随着孔径的逐渐减小,边坡的最大土壤流失量不断减小。In order to effectively control the water and soil loss of river bank slope in China,based on the water conservancy project in Linyi County,Shandong Province,this paper sets up soil and water loss model tests under different soil nail spacing and slope conditions,and deeply studies the application of soil nail slope protection technology in river bank soil and water conservation and slope management.The results show that:soil nailing slope protection technology is highly feasible in the control of river bank soil erosion,and the total soil loss under the condition of soil nailing slope protection is 82.67%less than that without soil nailing.With the increase of slope,the soil loss of slope presents a gradually increasing trend.With the increase of slope angle,the maximum soil loss increased by 13.46%,34.61%and 61.53%respectively.Under the same slope angle,the maximum soil loss of slope decreases with the decrease of pore diameter.
