摘要
大坝安全监测是对坝体变形、渗流稳定等进行监测,是大坝正常运行的重要标志。通过对某水库现场检查,坝体无明显裂缝、变形、溢出点等不利异常情况。安全监测数据分析:大坝水平位移稳定,垂直向呈整体下沉趋势,符合土石坝的一般变形规律;黏土心墙防渗效果良好,坝基渗流稳定,绕坝渗流及地下水位均无异常;大坝总体运行平稳。安全监测有效揭示了大坝变形特征及安全性态,为大坝后期安全运行管理提供了科学依据。
Dam safety monitoring is to monitor the deformation and seepage stability of the dam body,which is an important sign of the normal operation of the dam.Through the on-site inspection of a reservoir,the dam body has no obvious cracks,deformation,overflow points and other adverse abnormalities.Analysis of safety monitoring data:the horizontal displacement of the dam is stable,and the vertical direction shows an overall sinking trend,which conforms to the general deformation law of earth rock dams;The anti-seepage effect of clay core wall is good,the dam foundation seepage is stable,and the seepage around the dam and the groundwater level are normal;The overall operation of the dam is stable.The safety monitoring effectively reveals the deformation characteristics and safety behavior of the dam,and provides a scientific basis for the safe operation and management of the dam in the later stage.
