The Application of Anisotropy of Soil Properties in the Probabilistic Analysis of Landslides Activity.

In practice, in the performance of engineering and geological surveys anisotropy of soil strength is often considered not fully. One of the main problems in modeling the stability of rock landslide is an objective consideration of the influence of the parameters of cracks and other surface section on the calculation results. On the one hand, the study of fracture is always a certain measurement error, on the other, that the strength against cracking, in many cases, will determine the stability of the rock mass. It appears that the most promising approach is the simulation of fracture using the anisotropy of soil strength calculations of rock landslides. The article considers the influence of the anisotropy of the strength of the slope of the array of soil on the results of quantitative assessment of the overall stability of the slope. Strength criteria are considered grounds for taking account of anisotropy, the limitations of existing approaches to quantify the stability of slopes, describes the principles of probabilistic analysis in the analysis of the anisotropy of the strength properties of the soil. The possibility of obtaining estimates of probability of landslide deformation, which can then be used in geological risk analysis. [ABSTRACT FROM AUTHOR]
