Abstract:
The 3D finite element method based on strength reduction method was used to analyze the slope stability of a slope reinforcement project under natural conditions. The dangerous zone and most dangerous sliding surface of the slope were determined. On the basis, two reinforcement schemes were proposed, including the fitting-slope reinforcement and anti-slide pile reinforcement. The slope stability was analyzed under the two reinforcement schemes. The results showed that the 3D finite element method based on strength reduction method can provide reliable analysis of slope stability for the three-dimensional slopes with weak interlining and complex geological conditions. The three-dimensional finite element numerical simulation is necessary in the selection of slope reinforcement scheme.
