If the user wishes to skip the modeling process, the finished product of each tutorial can be found in the EXAMPLES folder in your SLIDE installation folder, in the files indicated. ![]() The slope stability analysis is rerun, and results compared with tutorial 5.tutorial5.sli tutorial6.sli (none)tutorial7.sliIt is recommended that the user follow the step-by-step instructions to create the models themselves. Examples of probabilistic analysis using SLIDE, can be found in the SLIDE Users Guide Part 2.Introduction3SLIDE DocumentationThe documentation for the SLIDE program is organized as follows: 1. A great deal of valuable insight can be obtained from a probabilistic slope analysis. Probabilistic slope stability analysis should be seen as a complementary approach to traditional deterministic (safety factor) analyses. This results in a distribution of safety factors, from which a probability of failure (or reliability index) for the slope can be calculated. By assigning a statistical distribution to one or more model input parameters, this allows the user to account for the degree of uncertainty in the value of the parameters. In a probabilistic slope stability analysis, the user may assign statistical distributions to input parameters, such as material properties, support properties, loads, water table location, etc. See the groundwater analysis tutorials at the end of this manual, for information.Probabilistic AnalysisSLIDE also has extensive probabilistic analysis capabilities. Due to the size of the watershed, the Rational Method is insufficient for determining the amount of water runoff generated, therefore the analysis will be conducted using the Soil Conservation Service (SCS) methods. This space was intentionally left blank Figure 3: Results from a Toe to Heel Analysis Hydrologic Analysis A hydrologic analysis is being conducted to determine the adequacy of the spillway located on the southern side of Odell Dam. In this figure, for a downstream slope failure, the F.S. Figure 2: Results from a Heel to Toe Analysis The analysis was for Figure 7, shown above, was conducted under the same process as in the Heel to Toe cross section, the only difference within this analysis is that the cross section was analyzed from Toe to Heel. Higher than 1.5 is considered safe as a standard of practice. The water line is necessary to determine how the soils will react when pressurized under water load conditions. ![]()
