Through the analysis on dam deformation,joint deformation of anti-seepage panel and seepage flow of the Huangfen Reservoir dam,the safety status of dam heightening project is evaluated.The analysis of monitoring data shows that the dam surface deformation,internal settlement,deep horizontal displacement and joint deformation of expansion anti-seepage panel are in the normal range when the reservoir is refilled after the dam is raised.Dam heightening has little effect on the impermeable wall.Compared with the water level of upstream reservoir,the water level of osmometer behind the impermeable wall has a great decrease,which indicates that the dam has a good impermeable effect.The reservoir dam is operating normally after the dam was raised.
