摘　　要：通过黄坟水库大坝变形、防渗面板接缝变形和大坝渗流分析,评价大坝加高工程安全状况。监测资料分析结果表明,大坝加高后水库重新蓄水,大坝表面变形、内部沉降、深层水平位移和扩建防渗面板接缝变形均在正常范围内;大坝加高对防渗墙影响较小,相对上游库水位,防渗墙后渗压计水位有较大跌幅,表明大坝发挥了较好的防渗效果;大坝加高后水库大坝运行正常。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.
