ABSTRACT
Chapter 15 discusses slope movement monitoring methods and predicting the time of failure, and the site conditions needed to be considered in selecting an appropriate monitoring method. Types of slope movement, and their relationship to slope stability, are discussed that include regressive, progressive movement and long-term creep. Surface monitoring methods include crack width meters, surveying, tiltmeters, photogrammetry, LiDAR, radar, global positioning system (GPS) and synthetic aperture radar (InSAR). Sub-surface monitoring methods include probes, inclinometers, time-domain reflectometry (TDR), inclinometers and microseismic recording. Movement data analysis includes time–movement plots, identification of failure mechanisms and matching point clouds to identify accumulation/depletion areas.
