Abstract

Abstract

The Baige landslide, which involved two large-scale high-elevation landslides, occurred in Boluo Township, Jiangda County, Changdu, Tibet. This catastrophic landslide blocked Jinsha River and formed a landslide-dammed lake. The consequent outburst flood caused downstream damage. The geomorphological and geological characteristics of the Baige landslide, which were defined by field surveys, engineering verification, remote sensing images, oblique photogrammetry and microscopic analysis of rocks, were investigated in combination with previous geological information. The results suggest that: (1) The Baige landslide was located on a valley-type structurally broken and loosened rock, which was developed along the Jinsha River tectonic mélange belt; (2) the slope is mainly composed of rock blocks with slightly deformed tectonic lens and intensely deformed dislocation zones (mylonite, cataclasite, and fault gouge), and it has been observed under microscope that rock structures have been greatly damaged, which reduced the rock strength; (3) both sides and the main scarp of the landslide were controlled by the fault fracture zone, which acted as the lateral and trailing cutting planes for the landslide; (4) the sliding layer of the Baige landslide was composed of the discontinuous dislocation zones, which were connected under the gravity unloading, and resulted in a multiple landslides of the slope in stages; (5) comprehensive start-up analysis of slope instability suggests the Baige landslide was a complex landslide with modes of moving and traction; (6) the Baige landslide occurred as a consequence of coupling of internal and external dynamics. In addition, the continuous eroding on slope toe by the Jinsha River, and the loose rock mass damaged under the gravity unloading also contributed to the Baige landslide. The Baige landslide event can not only provide information for studying the formation mechanism of large-scale landslides in the Jinsha River tectonic mélange belt, but also provide theoretical guidance for hazard prevention and mitigation in the region.
