摘　　要：三峡水库由于水位周期性涨落,导致岸坡侵蚀问题较为突出,水土流失较为严重,国内很多学者提出相应措施来治理消落带问题,但治理效果并不理想。鉴于此,通过室外拉拔试验,室内水槽试验对一种新型护岸结构特拉锚垫进行研究,分析特拉锚垫结构力学性能及防护效果。结果表明:特拉锚索最佳深度为1.2 m,草皮增强垫抗撕裂力为1.78 kN。通过室内水槽试验得到裸土段水土流失率达20%,特拉锚垫段不到8%,表明特拉锚垫防护结构对于土壤侵蚀和水土流失有较好防护治理效果,可为类似岸坡治理提供参考。Since the establishment of the Three Gorges Reservoir,due to the periodic rise and fall of the water level,resulting in the erosion of the shore slope is more prominent,soil erosion is more serious,many domestic scholars put forward corresponding measures to deal with the problem of falling zone,but the effect of governance is not ideal,in view of this,through the outdoor pull test,indoor sink test on a new type of shore structure Tra anchor pad research,analysis of the structural mechanical properties and protective effect of the tra anchor pad,the results show that:the best depth of the tra anchor rope is 1.2 meters,the grass pad strength is reinforced.The soil erosion rate of bare soil section was obtained by indoor tank test by 20%,and the tra anchor pad section was less than 8%,which showed that the protective structure of the tra anchor pad had a good protective effect on soil erosion and soil erosion,which could provide a reference for similar shore slope treatment problems.
