A New Paradigm for Slope Stability Analysis under Variably Saturated Conditions

摘要 Thislecture will highlight two major advancements in slope stability analysis thatstemmed from several multi-year field hydro-mechanical monitoring. The firstsignificant breakthrough is the capability to handle the transient field ofeffective stress in variably saturated slopes under rainfall conditions. Usingeffective stress analysis preserves the rigor, simplicity, and practicality ofthe classical slope stability methodologies (e.g., limit equilibrium). Thesecond is to quantify the field of local factor of safety (FS), which radicallydeparts from the classical one-FS-for-one-slope paradigm and allowsidentification of failure initiation and progression zones in slopes. The newhydro-mechanical framework for slope stability design and analysis onlyrequires three parameters in addition to the classical shear strength andseepage parameters. These parameters are used to uniquely define slopematerials’ constitutive relations of the soil water characteristic curve,hydraulic conductivity function, and suction stress characteristic curve.Several field cases are used to illustrate the validity, accuracy andsimplicity of the new hydro-mechanical framework for slope stability analysis.
