狮子滩水电站是建国后第一批完建的重点水电工程。作者结合狮子滩水电站多年运行后的实际情况 ,运用三维非线性有限元数学模型 ,针对影响溢流坝正常工作的主要工程问题展开研究 ,较全面地论证了坝基的抗滑稳定性 ,还对溢流坝坝体裂缝的成因进行了分析 ,并提出进一步提高坝基抗滑安全储备和减少坝体裂缝的工程措施
Shizitan Hydropower Station is the first batch of completed after the founding of key hydropower projects. Combined with the actual situation of Shizitan Hydropower Station after years of operation, the author studies the major engineering problems that affect the normal operation of spillway dam by using the three-dimensional nonlinear finite element mathematical model, and more comprehensively demonstrates the stability of the dam foundation against skidding. The cause of the flow dam body crack is analyzed, and the engineering measures to further improve the anti-slide safety reserve of the dam foundation and reduce the dam’s crack
