摘要

2018年10月10日和11月3日，西藏自治区江达县波罗乡白格村金沙江右岸同一位置先后两次发生滑坡堵江灾害，滑坡体方量分别约为1 000×104 m3和283×104 m3，其中第一次滑坡为高位、高剪出口、高速滑坡，第二次滑坡则为第一次滑坡牵引区进一步发展的结果。在堵塞金沙江近2 d及9 d后，滑坡堰塞湖蓄水量达到峰值分别为2.9×108 m3和5.24×108 m3，并分别在自然泄流和人工开挖泄流槽两种方式下开始从堰塞体右岸垭口处过流，其中第二次滑坡堰塞湖溃决洪水造成西藏、四川和云南3省（自治区）多处房屋、道路、桥梁和耕地受损，无人员伤亡。基于两次滑坡及溃决洪水受灾区现场勘测调查，并结合相关资料，对比分析了两次滑坡堰塞湖的处置及溃决洪水灾害情况，启示如下：越早进行人工干预，灾害越轻；为更好地应对今后可能出现的滑坡堰塞湖溃决洪水，水电站应提高设计标准并充分发挥其收蓄洪水的能力。

Abstract

On October 10 and November 3

2018

landslides occurred twice in the same position on the right bank of the Jinsha River in Baige Village

Boluo Township

Jiangda County

Tibet Autonomous Region. The volumes of the two landslides are about 1 000×104 m3 and 283×104 m3

respectively. The first landslide possesses high initial position

high shear outlet

and high speed. The second one is the further development of the traction zone of the first landslide. After blocking Jinsha River for nearly 2 days and 9 days

the water storage capacity of landslide barrier lake reached its peak values of 2.9×108 m3 and 5.24×108 m3

respectively

and began to flow through the right bank of the barrier dam through natural discharge and artificial excavated channel. The outburst flood of the second dammed lake caused much damage to houses

roads

bridges and cultivated land in Sichuan

Yunnan provinces and Tibet autonomous region

with no casualties. Based on field investigation on the two landslides and the flood-affected areas

the disposal of the two landslide dammed lakes and the outburst flood disasters were compared and analyzed based on relevant collected data. The revelations are as follows: the earlier the manual intervention

the lighter the disaster; In order to better deal with the possible outburst flood caused by landslide dammed lake in the future

the hydropower station should improve the design standard and enhance its capacity for flood collecting and storing.
