SIMILARITY OF DISPLACEMENT-TIME RELATIONSHIPS BETWEEN LABORATORY AND FIELD MEASUREMENTS OF PROGRESSIVE SLOPE FAILURES

Excavation of an open pit rock has long been known to alter the state of stress in the rock mass and consequently create new discontinuities which add to the existing joint systems. Behaviour patterns for movement of these blocks within a rock slope, prior to the eventual failure, were studied using rigid physical models and employing a specially designed base-friction table with an inclinable base. Additional results from the laboratory model studies show the existence of: (1) a relationship between horizontal block displacement and the normalized block distance from the slope face, with respect to elapsed time and the vertical block position in a given slope; and (2) a curvilinear relationship between maximum vertical block displacement and normalized block distances from the slope face, for various block layers in a given rock slope. The influence of different slope block configurations on the behaviour patterns for progressive movements of slope blocks is also discussed with respect to their resultant failure modes. The behaviour patterns observed in the laboratory model tests are compared with the results of some field measurements.
