摘　　要：根据飞来峡混凝土坝原型监测资料,选取每年最不利工况时坝顶水平位移监测效应量为计算序列,应用大坝典型监测量的小概率法,对大坝典型坝段坝顶水平位移的安全监控指标进行了初步研究,得出了坝顶水平位移的安全监控指标值,并结合2010年的实测值,分析了大坝的运行状况。结果表明,该坝2010年的水位、气温等环境量均未超过2000—2009年最不利工况时的环境量,并且2010年典型坝段坝顶水平位移的实测值均小于安全监控指标。Based on the observed data for dam safety monitoring at Feilaixia Dam,we selected the horizontal displacement for dam crest in the most unfavorable conditions every year as the calculating sequence.Typical small-probability method was used to do pilot study on monitoring index of horizontal displacement for dam crest at typical dam section.Safety monitoring values of horizontal displacement for dam crest were given in the paper.It analyzed the operation conditions of the dam,combining with the observed data in 2010.The results show that all environmental factors in 2010 such as water level and air temperature do not exceed environmental factors in the most unfavorable conditions of the period from 2000 to 2009.In these conditions,monitoring data of horizontal displacement for dam crest at the typical dam sections in 2010 are all less than safety monitoring values.
