Slope stability analysis considering seepage and stress coupling under water level fluctuation
نویسندگان
چکیده
The reservoir water level fluctuation is an important factor inducing the reaction of pore-water pressure, seepage and at last resulting in instability failure slope. A typical homogeneous slope conducted as example this paper, stress coupling effect considered, stability calculation analysis are carried out by using finite element method. results demonstrate that safety increases with rises, then gradually changes from decrease to stabilization. It should be noted decreases slightly during initial stage rising speed 0.2 m/d, which will probably lose its stability. On other, increase along drawdown, tends There a minimum when about 1/4 height, increasing drawdown speed, just 0.83 0.73 increased 0.20 m/d 5.0 m/d.

Slope Stability Analysis Under Combined Failure Criteria
Strength reduction finite element method (SRFEM) has been widely used to analyze the slope stability. Strength Reduction Factor (SRF) is yielded as the slope Factor Of Safety (FOS) when a running-though shear failure zone comes into being, in which the Plastic Element EQuivalent strain (PEEQ) is employed as the judgment of shear failure initiation in this paper. Moreover, the filed variable is ...
متن کاملThree Dimensional Transient Seepage and Slope Stability Analysis of Landslide Dam
Synopsis The failure of landslide dam formed by mass movements may occur by sudden sliding of the dam body. So, this study focuses on three-dimensional (3D) transient seepage and slope stability analysis of landslide dam. The 3D slope stability model coupled with transient seepage flow model is used for numerical simulations. Experiments are performed in the flume to measure movement of moistur...
متن کاملUncertainty of the Soil–Water Characteristic Curve and Its Effects on Slope Seepage and Stability Analysis under Conditions of Rainfall Using the Markov Chain Monte Carlo Method
It is important to determine the soil–water characteristic curve (SWCC) for analyzing slope seepage and stability under the conditions of rainfall. However, SWCCs exhibit high uncertainty because of complex influencing factors, which has not been previously considered in slope seepage and stability analysis under conditions of rainfall. This study aimed to evaluate the uncertainty of the SWCC a...
