| 英文摘要 | The 2000 Yigong landslide was one of the most catastrophic landslides worldwide, resulting in huge casualties and property losses. The dynamic process of the Yigong landslide was very complicated, especially for the initiation and entrainment mechanism during the landslide movement process. The topography, geological condition, traces left by the landslide, and distribution characteristics of the landslide deposits were determined by field investigations, combined with several years of monitoring the temperature and rainfall data in this region. The initiation mechanism of the Yigong landslide is presented. The main reasons for the landslide initiation are as follows: the strength reduction of rock masses (especially for the weak structural surface), the impact from years of freeze-thaw cycles, the superposition of glacier melting and heavy rainfall on the slope, and a slope that was almost at the limit state before the landslide. Laboratory tests and physical modeling experiments were carried out to study the entrainment process of this landslide. Combined with the topographic survey data and theoretical analyses, the entrainment mechanism during the movement process of the Yigong landslide is presented. The old landslide deposits on the lower slope collided with and were scraped by the high-speed debris avalanche, which resulted in the volume amplification of the landslide. The existence of water plays a key role during the landslide initiation and movement processes. |
