摘　　要：井下测量中经常会遇到导线点不通视,如果三个导线点互不通视,旁边又没通视的导线点时,可利用全站仪测量导线的边长和角度,经内业计算平差,得出相应的坐标值.这方法既能快速准确地指导施工,又可节省时间,不会因导线点不通视而耽误工程进度.Downhole measurements often encounter with the problem of wire point with invisibility. If the three traverse points do not pass,and there are no next to non intervisible traverse points,the total station measurement wire length and angle can be used for the inner adjustment calculation for obtaining the corresponding coordinate value. It can not only guide the construction quickly and accurately,but also can save time.

关 键 词：放样 不通视 导线点 平差
