Stability of Unsaturated Soil Slope Considering Stratigraphic Uncertainty
نویسندگان
چکیده
Stratigraphic uncertainty is widely present in nature, but it has not been well considered the stability analysis of unsaturated soil slopes past. In this study, slope evaluated based on borehole data considering stratigraphic uncertainty. Firstly, an enhanced coupled Markov chain model used to simulate Then, a finite element algorithm for automatically calculating safety factor (FS) and average groundwater table (AGT) developed. At last, hypothetical located stratum from Perth, West Australia analyzed using proposed under different schemes. The results show that with increase number, statistics FS AGT will monotonically or decrease. But trend mean values gradually approach eventually converge real values, standard deviations There linear relationship between deviation (or AGT) information entropy. are negatively correlated

Limit Equilibrium Analysis of the Influence of Matric Suction on Unsaturated Soil Slope Stability
In slope engineering, soils are commonly at unsaturated state. The question of how to apply unsaturated soil mechanics theory to the slope stability analysis has become a hot spot in today’s geotechnical engineering research. Based on the experimental research of how shear strength of residual soil varies with water content, reasonable computation modules can be created. By using limit equilibr...
متن کاملImpacts of Unsaturated Zone Soil Moisture and Groundwater Table on Slope Instability
The combined effect of soil moisture in unsaturated soil layers and pore-water pressure in saturated soil layers is critical to predict landslides. An improved infinite slope stability model, that directly includes unsaturated zone soil moisture and groundwater, is derived and used to analyze the factor of safety’s sensitivity to unsaturated zone soil moisture. This sensitivity, the change in t...
