Influence of spatial variability of permeability property on steady state seepage flow and slope stability analysis

Assessment of remedial measures to reduce exceedance probability of performance limit states in embankment dams

“…A combination of random field simulation, seepage analysis, and slope stability analysis was employed by Gui et al [10] to study the effects of stochastic hydraulic conductivity on the slope stability of an embankment dam and concluded that the reliability index is very sensitive to the uncertainty of saturated hydraulic conductivity. Srivastava et al [33] also investigated the effect of permeability parameter on the seepage and embankment stability using the finite difference approach. They assumed the permeability as a random variable with a lognormal distribution and reported that a lower value of correlation distance and coefficient of variation in the permeability parameter provides higher factor of safety values.…”

Characterization of Seepage Velocity beneath a Complex Rock Mass Dam Based on Entropy Theory

“…It is a challenge to investigate and model a fractured flow [4][5][6]. Therefore, statistical techniques, e.g., Monte Carlo simulations, random field theory, and the finite element technique, have been employed [7][8][9]. Although these techniques allow for the uncertainty to be considered more explicitly, studies of the seepage system in a complex rock mass dam still suffer from major problems such as the small sample sizes and limited information.…”

Probabilistic Assessment of Slope Stability for Earth-fill Dams Having Random Soil Parameters

“…MCSM was found to be more applicable and feasible for many kinds of geotechnical engineering problems including rock engineering. Srivastava et al (2010) studied the effect of spatial variability of permeability on seepage flow and slope stability. Adopting MCSM, for different coefficient of variation (COV) values of permeability, stability of a given slope was assessed by calculating factor of safety.…”
