Failure of slope generally sites along the slope of the stress concentration, while there are too many factors affecting stress distribution of slope, including the geometry of the slope, the strength parameters, the boundary conditions and constraints, etc. In this paper, considering the edge affect the elastic modulus of rock and soil slope, Poisson's ratio, shear strength parameters and other characteristics factors, by using finite element modeling to analyze the distribution forms of stress of the different slope, every factors affecting on the stress distribution of the different slope can be obtained. Through in-depth analysis, getting some understanding of regularity, it can be used to guide the engineering practice and has some promotional value.

The Stability

By analyzing the characteristics of expansive soil from Pingdingshan, China, the shear strength parameters at different water contents, dry densities, and dry-wet cycles of expansive soil are obtained. It is found that, at higher soil-water content, the internal friction angle is 0° and the shallow layer of expansive soil slope will collapse and destroy; this has nothing to do with the height of the slope and the size of the slope. The parameters of soil influenced by atmosphere are the ones which have gone through dry-wet cycles, and the parameters of soil without atmospheric influence are the same as those of natural soil. In the analysis of slope stability, the shear strength parameters of soil can be determined by using the finite element method, and the stability coefficient of the expansive soil slope can be calculated.

In seasonal frozen regions, shallow landslide hazards in soil slopes usually happen. The type of failure surface is always on the freezing and thawing surface in the soil slope. So the direct influence factor of soil slope failure is the soil shear strength of the freezing and thawing (F-T) surface. The shear strength of the soil is determined by the two parameters of Cohesion c and Friction angle φ. In this study model experiment of F-T soil interface with different aggregate materials is designed by alternating the F-T cycle times, then the parameters c and the φ were obtained. Finally the deterioration modal of the two shear strength parameters of soil interface was put forward. The results demonstrated when the slope stability in the seasonal frozen regions was analyzed using shear strength reduction method, the two deterioration modals can provide the data reference for the analysis.

Soil Shear Strength

In several places in the Banyumas Regency area, land movement problems have often occurred. Several locations have been declared as red zones, one of which is Beji, Cirahab Village, Lumbir District. With such regional conditions, it is necessary to conduct a study of the technical and mechanical properties of the soil in that location including moisture content, density and shear strength parameters related to the possibility of soil movement that will occur. From the results of the test and analysis using 3 specimens, the following data were obtained: water content of 20.22%, 30.36%, 40.31% with a cohesion value of 0.14 kg / cm2, 0.56 kg / cm2, 0.33 kg / cm2, and the internal friction angles of the soil are 30.22 °, 24.47 °, and 18.93 °. While the value of shear stress and displacement at maximum normal stress and moisture content of 20.22%, 30.36%, 40.31% are t(w1) = 0.68 kg / cm2,  t(w2) = 1.01 kg / cm2 ,t (w3) = 0.68 kg / cm2 and dn1 = 15.02%, dn2 = 10.02, dn3 = 13.35%. It can be concluded that the water content always has a very big influence on the value of the soil shear strength parameter. Therefore, the condition of the water content on the soil slope needs to be considered, and it is necessary to carry out further tests and more serious handling at that location.
