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 the three displacement meters of the Hexi Conductor Wall in Qingtongxia Hydropower Station, the displacement and horizontal displacement formulas of the displacement meter are deduced and demonstrated. The influence of the horizontal line body corner and the temperature of indium steel wire is analyzed. Both have little effect on horizontal displacement and forward canal displacement, and can be neglected in data analysis. This study makes up for the lack of monitoring data analysis of the Hexi dike displacement meter, and provides a calculation method for correctly understanding the deformation law of the guide wall.
