Abstract

Instability failures of locked-segment-type slopes are famous for their high start-up speed, strong suddenness, and serious harm. Therefore, research concerning the instability mechanism and reasonable instability prediction model of such slopes is urgently needed. The Chana landslide is chosen as an example of a typical locked-segment-type slope, and its failure and instability process is simulated based on the FLAC3D software platform. Through Fish programming language, the characteristics of acoustic emission (AE) events and energy evolution of the locked segment during the slope instability process are monitored. Based on the simulation results, the failure mode and instability mechanism of the Chana slope are revealed, as well as the damage evolution process of the locked segment that controls the stability of the Chana slope. Based on the critical displacement criterion, the critical instability displacement of the Chana landslide is retroactively predicted, and a good prediction effect is achieved. In addition, it is found that when the critical displacement criterion is adopted for predicting the locked-segment-type slope instability, like the Chana landslide, the crack width at the back edge of the slope can be selected as an alternative value to replace the shear displacement of the locked segment. The relevant research results have an important theoretical value and application prospects for slope instability disaster prevention.
