介绍了西藏冰湖灾害的分布、特点,分析了冰湖溃决成因及溃决方式,提出了冰湖灾害应急处理措施,并以紧邻的皮达湖、龙巴萨巴湖2座冰碛阻塞湖为例,确定了应急除险设计中冰湖的泄流量、开挖渠道的断面尺寸及施工变更情况,除险后消除了冰湖溃决险情,同时也截断了皮达湖、龙巴萨巴湖之间的水力联系,除险效果很好。 This paper introduces the distribution and characteristics of glacier disasters in Tibet, analyzes the cause of the collapse of the ice lake and the ways of its collapse, and puts forward the measures to deal with the disasters of glacial lakes. Taking the adjacent lake blocks of Pieda Lake and Longba Siba Lake as examples, , Determine the discharge of the ice storm lake emergency design, cross-section excavation channel size and construction changes, eliminating danger of the ice lake after the calamity, but also cut off between the Pieda, Long Barba Lake between Hydraulic contact, extermination works well.
