Prestressed Anchor Cable Supporting give full play to the self- supporting capacity of the rock mass , adjust and improve the rock mass strength and self - stabilizing capacity , and can provide a powerful of jointed rock slope , rock faults , weak with active means of support , this can not be achieved by conventional non- prestressed supporting measures . The prestressed anchor around the high rock slope reinforcement support technology closely integrated engineering design needs , and this paper through numerical simulation , in order to build based on the large - scale analysis system FINAL Jinping I Hydropower Station spandrel groove slope for instance , proposed the the new anchor simulation methods consider prestressed Anchor construction process , the numerical simulation of the system analysis of spandrel groove slope stability and ANCHORING measures to optimize the contrast of the difference between the different simulation methods . And numerical experiments on the High Slope layered excavation , blasting under stress wave slope prestressed anchor cable dynamic bearing characteristics , the main findings : 1 , considering anchor cable construction process of new prestressed Anchor simulation method , optimized numerical simulation study of the system stability and the slope of Jinping Hydropower Station under construction on the left bank of spandrel groove ANCHORING measures , discussed the reinforcement of prestressed anchor group mechanism, provided the basis for the reinforcing Design for of Jinping high- slope . From the quantitative point of view reveals blasting under stress wave slope prestressed anchor group dynamic bearing characteristics , transient tensile force of the impact Prestressed Anchor the incremental relative amount of the size of the main factors were the distance , the rock mass damping , the maximum single- ring bLASTING prestressed reference tonnage, for the high slope blasting excavation and Prestressed Anchor construction .
