摘　　要：通过对施工期至蓄水初期的马鹿塘水电站二期工程面板堆石坝开展系统的安全监测,整理、分析主要监测断面的资料,得出了大坝的实际工作性态。鉴于自蓄水以来库水一直处于较低(远低于正常蓄水位)的条件下坝体变形已较大,而且坝体变形的时效作用仍将延续,因此,在下阶段水位上升过程中,必须加强大坝的变形和渗流等监测,并及时对监测资料进行分析反馈,以便采取相应对策。In Malutang Hydropower Station Phase II Project,systematic monitoring of the concrete face rockfill dam during the construction period and the early impoundment period is carried out.Then,the monitoring data of main dam sections are analyzed and the actual working conditions of the dam are obtained.The results show that the deformation of the dam body since the impoundment is rather large when the water is at a low level that is far below the normal storage level.Considering that the time effect of the dam deformation will continue,the monitoring on the deformation and seepage of the dam should be further emphasized during the following water level rising process,and the monitoring data should be analyzed timely so that corresponding measures could be taken.
