摘　　要：为了掌握乌江渡水电站坝顶在外界环境与自身条件作用下产生的向上、下游方向的位移,采用视准线法(活动觇牌法)和威尔特T3经纬仪对坝顶水平位移进行监测,分析了库水位、温度和时效等因素对坝顶水平位移的影响,指出坝顶水平位移观测存在的问量并提出改进措施。经对多年观测数据分析可知,大坝处于安全运行状态。In order to master the upstream and downstream displacement of the dam crest in Wujiangdu Hydropower Station under the action of external environment and its own conditions,the horizontal displacement of the dam crest is monitored by collimation line method(moving sign method)and Wilt T3 theodolite,and the influence of factors such as reservoir water level temperature and ageing on the horizontal displacement of the dam crest is analyzed.The existing problems in the observation of the horizontal displacement of the dam crest are pointed out and the improvement measures are put forward.According to the analysis of observation data for many years,the dam is in safe operation.
