摘　　要：Reservoir revetment in cold regions is often damaged by frost due to the joint action of low-temperatures and cryogenic environment in winter. This damage reduces or even eliminates the function ofthe reservoir revelrnent. In this paper, practical problems in engineering were analyzed for the drainage pumping station of Tuanjie Reservoir. Based on a tradifional method of analysis and calculalion, fiacture mechanics was iricorporated to provide quantitative analysis and calculation on the problem of anti-freeze damage from the viewpoint of fracture mechanics. Thus, a new idea is put forward to resolve anti-freefing ofreservoir slope proteclion in cold regions.Reservoir revetment in cold regions is often damaged by frost due to the joint action of low-temperatures and cryogenic environment in winter.
