Review of Landslide Stability Analysis Method

Abstract

The stability analysis and evaluation is the base of the landslide prevention, at the same time have improvement guidance to the landslide prediction. Divided the Chinese landslide stability analysis of research history into three stages:①experience analysis and evaluation stage;②half experience and semi theoretical analysis and evaluation stage;③theoretical development and the deeping stage. Described the research situation,trend and existing problems of the slide stability analysis and evaluation,get a clear conclusion,put forward my own understanding.

State fusion entropy for continuous and site-specific analysis of landslide stability changing regularities

“…Analysis of landslide stability as well as its changing regularities plays a significant role in risk assessment at site-specific landslides (Wang et al, 2014). For this concern, many stability analysis methods have been proposed, such as Saito's method, limit equilibrium method (LEM) and finite element method (FEM) (Saito, 1965;Duncan, 1996;Griffiths and Fenton, 2004).…”

Stability analysis of accumulation body based on monitoring results of deep displacement

“…The stability evaluation method for accumulation body includes qualitative analysis and quantitative analysis (Zhu and Hou, 2007;Zhang and Wang, 2009;Wang et al, 2014). The former includes the natural history analysis method (Duncan, 1996), the engineering geological analogy method (Chen and Liu, 2007), the graphic method (Xia and Li, 2002), It makes a judgement by intuition and experience, relying on the nature and the characteristics of the object to be analyzed including its past and present existence states, and its evolution law.…”
