“…However, these deterministic methods do not address explicitly the uncertainty of soil parameters. Thus, the probabilistic approach needs to be introduced in the reliability-based design [7]. The probabilistic approach and reliability analysis method provide a rational way to account the uncertainties from different sources and estimate the probability of satisfactory performance in systematic way.…”

“…The Monte-Carlo simulation method is commonly used in reliability analysis used for wide range of problems in geotechnical engineering. The Monte-Carlo simulation method is used to get the probability density function of output variable, such as safety factor, percentage of probability of failure and reliability index, from random variable distribution of shear strength parameter, represented in distribution functions [7].…”

Soil uncertainties should be considered in the safety and economic evaluation of geotechnical structures. The impact of uncertainties in risk assessment help engineer in deciding a safer and economically feasible design of geotechnical structures. This paper studies the effect of red clay soil strength uncertainties on the highway excavated slope geometry designs. Different slope geometries are considered: slope angles of 27, 34, 45 and 63 degrees and slope heights of 5 m, 10 m and 15 m. The probabilistic analysis of slope stability is conducted using SLOPE/W to obtain the probability of failure, as well as the failed soil mass volume. The resulting probabilities are used in the quantitative decision making analysis on slope geometries. The Expected Monetary Value (EMV) derived from the construction costs, the repair costs, as well as the highway closure losses for different Levels of Service, is used in the analysis. The decision-making analysis results provide an overview of how the consequences of slope failures determining the decisions made. The consequences of slope failure indicate the design should lean on the gentle slope.
