EXPERIMENTAL STUDY OF ENGINEERING SLOPE HAZARDS OF MULTI-LAYER AND MULTI-LEVEL LANDSLIDES

The Zhangjiaping landslide has multi-layers and multi-levels. To model excavation of the slope, the most typical cross-section is selected as the physical model prototype. During the experiment, the slope stability is simulated under the influence of rain by even capillary flooding method. By comparing two experiments with and without an anti-slide structure, the authors gain an insight into the destabilization mechanism of this slope, and the reinforced effect of anti-slide structure.
