摘　　要：结合青铜峡水电站河西导墙3条变位计的布设情况,推导和论证了变位计的水平和顺渠向位移公式,并对其中的水平面线体转角和铟钢线温度影响进行了分析,认为两者对水平位移和顺渠向位移的影响很小,可以在资料分析中予以忽略。该研究弥补了河西导墙变位计监测资料分析存在的欠缺,为正确掌握导墙的变形规律提供了计算手段。According to the layout of three displacement meters,a formula for the horizontal displacement and the displacement along the canal of the Hexi guide wall of the Qingtongxia Hydropower Station are calculated and demonstrated,and the effect of the horizontal rotating angle and temperature change of indium and steel line body on displacement is also analyzed.On this basis,a conclusion is drawn：the effect is small and may be ignored in data treatment.The study makes up for the deficiency in analysis on monitoring data from displacement meters in the Qingtongxia Hydropower Station,and provides a calculating means for finding out the displacement characteristics.
