The routine can be used to fit two-dimensional data, but the fitted data (the ydata argument) must be repacked as a one-dimensional array first. It indicates that analyzing slope stability with strength reduction method is feasible. Non-linear least squares fitting of a two-dimensional data. The analysis results show that the artificial rock mass slope is basically stable. In this analysis, static and dynamic instability criterions are enumerated, and the static and dynamic safety factors are calculated with the developed criterions of the displacement mutation, respectively. Alavi 74 used FLAC3D to study the eect of the full- shotcrete anchor support on surrounding rock under dy- namicloading.Srikrishnanetal. The static and dynamic stability analysis on the artificial rock mass slope of WuAn power plant in China is carried on respectively in this paper by using the strength reduction method and FLAC3D software. Firstly, a mechanical relationship model of a bolt-drawing, anchoring interface was established to obtain the equations of the axial force and obtain shear stress distribution as well as the. Based on this background, full-stress anchoring technology of bolts was proposed. Many people modeled it as a square or circular shape in Plaxis 3D but no one able to model it as the actual curve-linear shape. For some common shapes of openings, the analytical solution is compared with numerical computations performed with FLAC3D (ITASCA 2011). An analytical solution is derived for arbitrary cross sections.

o Construct the rule base (Break down the control problem into a series of IF X AND Y, THEN Z rules based on the fuzzy logic rules). In this paper, we study a more complex situation where the tunnel axis is assumed to be parallel to the plane of isotropy. It is designed to accommodate any kind of geotechnical engineering project. FLAC is used for analysis, testing, and design by geotechnical, civil, and mining engineers.

Therefore, the stability analysis and evaluation on rock slope is of great significance. The traditional anchoring method of bolts has insufficient control over the surrounding rock of the coal roadway. Qadri Hamarsheh 4 o Construct the fuzzy logic membership functions that define the meaning or values of the input and output terms used in the rules. FLAC, Fast Lagrangian Analysis of Continua, is numerical modeling software for advanced geotechnical analysis of soil, rock, groundwater, and ground support in two dimensions. The mine comprises 20 orebodies of varying size, shape and orientation. For a long time, rock slope stability problem is always an important research issue in the field of geotechnical engineering, which is related to human life and property safety as well as engineering security and efficiency. All our 3DEC and FLAC3D users can benefit from lower prices on the pre-purchase.
Abstract: This paper focuses on stability analysis of an artificial rock mass slope by a nonlinear finite element method (FEM).
