摘　　要：为了提高地下工程竖井定向精度,阐释了连接四边形法竖井定向方法,用一个角和一条边为参数确定对称四边形,构建了连接四边形严密平差模型,采用间接平差进行网形精度评估。编写程序遍历条件角和条件边计算定向边精度,绘制等值线,定量分析连接四边形法最优图形。该研究对于地下工程竖井定向具有实际应用价值。In order to improve the accuracy of underground engineering vertical shaft orientation,the connecting quadrilateral method vertical shaft orientation method was explained.A symmetric quadrilateral was determined using one angle and one edge as parameters,and a rigorous adjustment model for connecting quadrilaterals was constructed.Indirect adjustment was used to evaluate the accuracy of the mesh.A program was developed to calculate the accuracy of directional edges for different conditional angles and edges,draw contour lines,and quantitatively analyze the optimal shape of quadrilateral connections.This study has practical application significance for the orientation of underground engineering shafts.
