| For a long time, treatment of high slope always attracts the interests of scholars andtechnicians. This paper studied the slope stability using the strength reduction methodbased on the high slope of Yinxianghe, proposed three treatment schemes, then selectedthe optimum one, finally optimized the parameters. The analysis is discussed mainlyfrom the aspects of stability safety factor, displacement field, Latent sliding surface andMises stress, the results can bring about some particular consulting significance to othertreatments of high slope diseases. The main conclusion follows:The safety coefficient of the natural slope is0.967, the slope is unstable, and thereis obvious stresses concentrating at the foot of the slope. Three treatment schemes inslope cutting scheme, anchor lattice frame scheme and anti-slide pile scheme areproposed, the results shows that the anchor lattice frame scheme is the optimal one.Studied the slope stability affected by the position and width of the unloading plateau,obtained the preferred schemes.Discussed the slope stability with the parameters of anchor varies. The safetycoefficient of the anchor lattice frame scheme increases logarithmically as the anchorlength raises, and increases as the length of anchorage raises, presents cubic parabolalaws as the anchor orientation rises. The maximum value of soil displacementssignificantly increases when the anchor length raises, the deformation ability of theslope improved significantly.Studied the slope stability affected by the height of the lattice beam. The resultsshows that, the height of vertical and horizontal lattice beam have a relatively smallimpact on the stability safety factor. The maximum value of soil displacement and shear stress increment increases gradually with the height of vertical lattice beam rises. Whenthe height of the horizontal lattice beam increases, the maximum value of soildisplacement rises slowly, and the shear increment almost remains the same. |
