Slope Stability Monitoring Using a Ground Based Portable Radar Interferometer

The extents of a landslide are important to design engineers in order to determine the amount of driving force causing the slide and the amount of mitigation required. The current practice of using slope inclinometers, piezometers and survey control points located within the face of the sliding mass does identify the sliding mass, but does not determine the extents or limits of the slide. The landslide occurring across Highway 84 and Interstate-30, located southwest of Malvern at mile marker 95.7, has been instrumented using piezometers, slope inclinometers and survey control points. Using the data obtained from the instrumentation, the landslide is moving as a slide block, with the failure surface located 74 feet below the interstate. The extents of the slide are unknown resulting in a conservative design remediation recommendation.
