摘要：In the analysis of strength reduction finite element method, there are a variety of computational judgments of instability. Therefore, it is necessary to approach the applicability and discrepancy of different instability criteria. Based on the thought of real-time visual analysis, this article gives the research and development of corresponding visual programs, and finishes the real-time visual display technique of view about the relationship between three instability criteria and the strength reduction factor in computation of strength reduction finite element method. Then this article makes the numerical computation and analysis of a rather complicated slope. Research indicates that with the combination of finite element computation of strength reduction and the visual technique of computer, the sliding surface and stability of a slope can be analyzed intuitively. For slopes with local sliding surface or complicated shapes, safety factors are somewhat different because of employing the different instability criteria in the computation of strength reduction finite element.
