金沙江上游构造破碎、岩体结构复杂,区内大型‑巨型滑坡发育,历史上发生过多次滑坡堵江事件。圭利滑坡位于西藏江达县金沙江西岸,滑坡变形严重,大小拉裂缝、垮塌几乎覆盖整个滑坡,变形程度有不断增加的趋势,失稳后将对金沙江下游造成巨大威胁。在野外调查的基础上,通过对金沙江上游圭利滑坡发育特征的分析,选取Massflow数值计算模型对该滑坡失稳运动过程进行预测分析,获取了滑坡在不同时刻的堆积状态及运动速度。结果表明,滑坡整体运动时长约为40 s,最大滑动速度达到31 m/s,最大堆积厚度为51 m;前缘向两侧扩散的最大距离约为220 m,并全部堵塞金沙江;滑坡各区域的速度曲线反映出滑坡运动过程具有突发性、彻底性、整体性、流态性的特点。
The upper reaches of Jinsha River are tectonically fragmented, with complex rock structures and large - giant landslides. Many landslides blocking events have occurred in history. Guili landslide is located on the west bank of Jinsha River, Jiangda County, Tibet. The overall deformation of the landslide is serious, with five deformation areas and five developed large tension cracks. According to the displacement data monitored by GNSS, the deformation of the landslide is increasing, which poses a great threat to the lower reaches of Jinsha River. Based on detailed field investigations, this paper analyzes the development characteristics of the Guili landslide. The Massflow numerical calculation model is selected to predict and analyze the movement process of the landslide. We obtain the characteristic parameters such as movement distance, accumulation thickness and velocity kinetic energy of the landslide at different moments. The simulation results show that the overall movement of the landslide takes about 40s, the maximum sliding speed reaches 31m/s, and the maximum accumulation thickness is 51m, mainly accumulated in the river channel. The maximum distance of the front edge spreading to both sides is about 220m. The velocity curves of each area of the landslide show that the movement process is characterized by suddenness, thoroughness, wholeness, and fluidity. Early identification methods and numerical simulation techniques have guiding significance for geohazard mitigation.
