潘口面板坝施工及蓄水初期安全监测成果分析

为了解潘口水电站面板堆石坝在施工期及蓄水初期的工作性态，分别进行了大坝外部位移、坝体内部位移、面板应力应变、渗流等项目的监测。监测成果分析表明，大坝沉降、内部位移、周边缝的变形等相比于同级别其他面板堆石坝的实测值均略偏小。大坝变形符合堆石坝的一般规律，蓄水后无明显突变和异常。初步判断，大坝的工作状态是正常、安全的。

Safety monitoring analysis of Pankou faced rockfill dam in construction and preliminary water impoundment period

For obtaining the working performance of Pankou faced rockfill dam in construction and preliminary water impoundment,we conducted the safety monitoring of dam surface deformation,dam internal deformation,strain and stress of dam slab and seepage flow.The results show that the dam settlement,internal deformation and displacement of peripheral joints are relatively lower than other faced rockfill dams of the same class.The dam deformation laws are consistent with normal conditions with no mutations and abnormal phenomena.It is concluded preliminarily that the working status of the dam is normal and safe.
