| Abstract: | 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 of the reservoir revetment. In this paper, practical problems in engineering were
analyzed for the drainage pumping station of Tuanjie Reservoir. Based on a traditional method of analysis and calculation, fracture mechanics
was incorporated 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-freezing of reservoir slope protection in cold regions. |
