Abstract:

Due to the limitation of the numerical models of anchors by finite element method (FEM) in geotechnical engineering at present, an anchor model which is fit for the strength reduction FEM is put forward. Strength reduction FEM considering the anchor model is proposed. The corresponding program is also developed; and the proposed model and method are tested by a case study calculation results of a simple rock slope reinforced with anchors. At last the model is used in evaluation of a soil slope stability; and the results of this example indicate that the model is convenient and feasible.

Key words: slope, anchor, calculation model, finite elements model, strength reduction
