Spatial Optimization of Anchors for Slope Stabilization
Numerical simulation was performed with Flac3D to study on spatial factors of anchors. For the studied case, factors affecting slope stability with reducing effect are: length of middle level anchors, length of lower level anchors, length of upper level anchors, average elevation of anchors, vertical spacing and inclination of anchors. Displacement mainly occurs in middle-upper part of slope. Maximum tension of anchors appears on the middle level anchors. For the given slope, the best inclination of anchors is suggested to be 17° from horizontal; optimized uniform length of anchors should be 8m. Optimal horizontal spacing of anchors is determined to be 3m. Diamond-shaped layout has better reinforcing effect than rectangular layout. Anchors should be installed without overlap of adjacent reinforcing areas. Unreinforced soil mass should be separated into small blocks by adjusting spacing between anchors so as to achieve the best reinforcing effect.
