As you can see in the plot below, a weak layer cohesion Occurred the safety factor is by definition equal Value and enter a safety factor value = 1 (since failure has Now compute the analysis and view the sensitivity plot. This willĮffectively vary the cohesion between 0 and 20 kPa for the Will guess at the mean value of cohesion (10 kPa) and enter We can define a single variable (weak layerĬohesion) in the material statistics dialog. Layer is known (15 degrees) but the cohesion Safety factor, strength parameters, pore pressure).įor example, lets assume that the friction angle of the weak cohesion orįriction angle of one material), if we assume that all other Sensitivity analysis allows you to determine the value of a Sensitivity Analysis for Back Analysis of a Single Variable Known (cohesion = 17.5 kPa, friction angle = 30 degrees). The properties of the strong material are The location of the water table at failure is known (blue line). Red line which traverses through the weak layer. Layer (green material) surrounded by stronger material above and Slide 6.0 does have an explicit optionįor back analysis of support force to achieveĪ specific factor of safety as described later in thisįor the purpose of this discussion we will consider theįollowing slope model. To the determination of required material properties or supportįorce in order to achieve a specified factor Note that back analysis does not necessarily imply that failure We will discuss each of these various methods in the following Probabilistic analysis for two correlated variablesĪdvanced probabilistic methods for simultaneous analysis of Sensitivity analysis for individual variables Manual trial and error to match input data with observed There are a variety of methods for carrying out back Of material properties, it is possible to carry out backĪnalysis using the sensitivity or probabilisticĪnalysis modules in Slide, as we will describe in this Have an explicit option for the back analysis The back analyzed properties can be used to design remedialĪlthough the current version of Slide (version 6.0) does not Or other conditions at the time of failure. Known (or assumed) failure surface, some form of back analysisĭetermine or estimate the material shear strength, pore pressure When a slope has failed an analysis is usually carried out to groundwaterīack analysis of support force for required factor of safety In this article we will discuss the following topics:īack analysis of material strength using sensitivity orīack analysis of other parameters (e.g. The answer is YES, as we will discover in this article, whichĪnalysis using Slide and other Rocscience software. A question we are frequently asked is, Can Slide do back
