Abstract

Embodiments of the invention provide a fuzzy classification technology-based slope reliability parameter obtaining method and apparatus, and belong to the field of data processing. The method comprises the steps of generating k training sample vectors through an orthogonal design method according to mean values and standard deviations corresponding to m uncertainty parameters respectively; according to the k training sample vectors and one or more deterministic parameter values, obtaining slope stability coefficients corresponding to the k training sample vectors through a slope stability analysis method; by taking the k training sample vectors as independent variables and taking the slope stability coefficients corresponding to the k training sample vectors as dependent variables, forming a mapping relationship, and obtaining a mapping relationship expression through a support vector machine algorithm; and according to randomly generated N to-be-tested sample vectors obeying joint probability distribution, the mapping relationship expression and a preset instability state fuzzy judgment function, obtaining slope reliability parameters. The slope stability is quantized through the instability state fuzzy judgment function, so that the accuracy of the slope reliability parameters is improved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and device for acquiring slope reliability parameters based on fuzzy classification technology. Background technique [0002] Slope stability is a common problem in the research of industrial and agricultural production and geological hazards. The study of slope stability has gone through two leaps, that is, the leap from qualitative judgment to quantitative analysis, and the leap from certain theory to uncertainty theory. [0003] Mathematically, uncertain problems are finally converted into several deterministic problems for processing, and the general solution mode is: the deterministic analysis method is used as the core, and the reliability analysis method is nested outside. In current slope reliability research, the deterministic analysis method core is dominated by the traditional limit equilibrium method, and the numerical method has an upward trend in recent year...
