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 کاملAn Evaluation of Slope Stability Classification
An overview is given of a series of classification systems used for rock slope stability analyses. Calculation methods and parameters used seem not always appropriate for slopes stability and could be improved. Based on this evaluation some new ideas developed of how a system for slope stability assessment could be designed without inherited legacies as parameters related to underground excavat...
متن کاملEstimation of Water Retention Curve for Unsaturated Fine Soils
In order to obtain the soil water retention curve of an unsaturated soil which is defined as the relationship between water content and suction, extensive laboratory tests are essential. These laboratory tests are usually costly and time consuming. Moreover, for most practical problems, it has been found that approximate unsaturated soil properties are adequate for analysis. Thus, empirical pro...
متن کاملNumerical Simulation of Stability Analyzing for Unsaturated Slope with Rainfall Infiltration
Rainfall infiltration exerts great effect on the stability of soil slopes. Based on the actual rainfall data, saturated-unsaturated seepage theory and the mechanical theory of unsaturated porous media, numerical simulations were conducted to examine the seepage field of saturatedunsaturated slope during rainfall infiltration in this paper. The influence of the coefficient with rainfall duration...
