Seepage stability analysis and safety evaluation of the main dam of Dayechong reservoir
As a key medium-sized reservoir in Dongkou County,Shaoyang City,Hunan Province,the seepage status and safety of the main dam of Dayechong reservoir have a great impact on the ecological environment of surrounding areas and the safety of people's lives and property.Based on the actual geo-logical survey results,the safety indexes such as seepage pressure,saturation line and seepage flow per unit width of dam body under different working conditions are analyzed by combining field measure-ment,theoretical analysis and numerical simulation.The research results show that the existing design scheme of the main dam of Dayechong reservoir can play a certain role in seepage control,but the seep-age pressure of dam body is high,the saturation line is high,and the seepage flow per unit width is large.Due to the influence of dam seepage,the dam stability will gradually decrease,so effective reinforce-ment schemes and preventive measures should be taken,and the dam safety management and monitor-ing means should be strengthened to improve the safety and stability of Dayechong reservoir.
