Research On Modeling Technology For Three-dimension Analysis Of Irregular Slope Stability In Surface Mines And Its Applications

The traditional two dimension slope calculation can’t make comment on the slope stability objectively. The slope stability not only has something to do with hydrogeololgy, but also with the concave and convex extent of the slope. The traditional method can’t present the three-dimensional effect of the slope, so it’s not objective to make comment on the slope stability.The text tries to present the three-dimensional effect of the slope by the three-dimensional model, and takes the example of Jilinguole2strip mine irregular three-dimensional slope, researching the three-dimensional model method of the irregular slope stability by AUTOCAD and ANSYS, founding the FLAC3D.He analyzes the stability of the Jilinguole2strip mine south slope by numerical simulation analysis. The slope is in the stable condition, affirming that the potential landslide type of the slope is the mansard damage. It determines the biggest displacement point coordinates.By the ways of the numerical simulation analysis and limit equilibrium analysis integration, determining the potential typical section, adopting the simplified Bishop Method, simplified Janbu Method and Morgan Winston-Price Method tocarry on comprehensive evaluation to the most dangerous sliding surface stability. The smallest stable factor is1.385, so Jilinguole2strip mine is in the stable condition.
