11 Analysis 2016(v1.1) Release Notes 1. [Slope] Probability and Sensitivity Analyses Almost all input parameters can be assigned a probability distribution, and compute a probability distribution of the resulting safety factors. Once the probability distribution of the safety factors are known, other quantifying parameters, such as the probability of failure can be determined. With a uniform probability distribution, the probabilistic scheme can also be used to conduct a sensitivity analysis.

13 Analysis 2016(v1.1) Release Notes 2. [Slope] Optimization Method in LEM Optimization method is introduced in slope stability analysis using LEM. It is the method finding the safety factor of critical failure surface by generating approximation model about relationship between the movement of polygon and safety factor and changing the slice of polygonal failure surface gradually. In other words, failure surface where the lowest safety factor is occurred is searched through iterative calculation from the failure surface where minimum safety factor is occurred.
