摘　　要：本文针对格里桥水电站表孔弧门的特点采用全站仪测量三扇表孔弧门的门槽埋件和弧门侧水封工作面三维坐标。通过计算得出闸门表孔弧门门槽埋件和侧水封的垂直度和跨度,并对比分析了门槽埋件和侧水封跨度的匹配度。根据表孔弧门门槽埋件和侧水封的垂直度和跨度数据,分析了闸门漏水的原因,并提出了闸门漏水处理方案。This paper addresses the characteristics of the table hole arch gates at the Geliqiao Hydropower Station by employing a total station to measure the three-dimensional coordinates of the embedded components in the gate grooves and the water sealing surfaces on the sides of the three table hole arch gates.Through calculations,the verticality and span of the gate grooves’embedded components and the water sealing on the sides are determined.A comparative analysis of the matching of the gate groove embedded components and the side water sealing is conducted.Based on the data regarding the verticality and span of the gate groove embedded components and side water sealing,the causes of gate leakage are analyzed,and a solution for addressing the gate leakage is proposed.
