摘要：Take Yimeng pumped storage project as a case of a folded-line concrete face rockfill dam, three-dimensional static finite element stress and deformation analysis is carried out to simulate the characteristics of the dam during construction and storage period, the deformation mechanism of the folded-line concrete face rockfill dam is analysed, and the stress and deformation law of the folded-line concrete face dam is obtained. The analysis shows that the large turning angle of panel is the most obvious factor to increase tensile trend and degree of face slabs and peripheral joints, the connecting plate has contribution to the improve stress and deformation behavior of slabs and peripheral joints. It is suggested to strengthen the research on the tensile properties of the slabs, the connection plate and the waterproof structure.
