| 摘 要： | 2000年4月9日20时05分，西藏波密县易贡乡发生的大型山体崩滑，造成极大危害。在野外调查基础上，运用离散单元法模拟该崩滑体破坏、运动的全过程，此次灾害为扎木弄沟源头的山体崩塌，振动引起沟内崩坡积物发生沙土液化而随崩塌体一起运动，形成高速碎屑流的破坏运动机制，与实际情况较为吻合。

NUMERICAL SIMULATION ON OVERALL PROCESS OF YIGONG SLUMP AT BOMI, TIBET |
| |
| Abstract: | On April 9,2000,a big slump happened at Yigong,Bomi county of Tibet and caused heavy damages and losses,however without death.Based on field investigation,the full course simulation of the slump is carried out in this paper.The results of simulation show that shake of the avalanche occurred at the end of the Zhamunong valley trigged the sliding of accumulating materials in the valley at first,and then they moved at a high speed together.When rushing out they were disassembled and formed debris flow with high speed. |
