 GIS-Based Kinematic Slope Stability Analysis Track: Mining and Geosciences Author(s): Tim Mote, Derek Morley, Timothy Keuscher, Todd Crampton Kinematic slope stability analysis addresses Dip-Slope Failure, failure along subsurface bedding planes, and Wedge Failure, block failure along a plunge line created by the intersection of two structures (faults and/or joints). A relationship between the bedding planes (strike and dip) or plunge lines (trend and plunge) and the orientation of the hillside (aspect and slope) determine the kinematic stability of a slope. We apply a kinematic model to address slope stability for canyon landfills in Southern California. By compiling field mapping and borehole logging of geologic structures (location, type and orientation) into the GIS, we create a representative model of the subsurface across the study area. Spatial analysis of the geologic model and the hillside model will determine kinematic slope stability and identify areas suitable for development. Our simplistic approach does not account for cohesive strengths and assumes that slide planes are frictionless.
