摘要 本文介绍了大型工业建设场地建筑方格网测设中用无对角线四边形法在主方格网内加密建筑方格网的方法。该法测角工作简便,且根据网形预先计算出协因数阵,制成Q_x值表,可方便地用作测角精度估算和加密方格网平差计算。 This paper presents a method to densify the grld squares for buildings in large sites of industrial construction using non-diagonal quadrilateral method. The angle measurement works are rather simple. The weight coefficient matrix should be firstly calculated according to the configuration of the square grid for buildings. Then, the Q_x table is prepared. It can be conveniently used to estimate the angle measurement precision and calculate the densified network adjustment.
