纵断面直角坐标转换在斜井测量中的应用

Application of Vertical Section Rectangular Coordinate Transformation in Incline Survey

建立与坡度相关的斜井纵断面方向的直角坐标系进行施工放样测量,相对于常规的利用坡度计算斜距,推算高差进行斜井放样的方案无论是现场的施工放样还是内业数据的处理中都具有简便、高效、直观的优点,有利于现场施工放样与断面图的绘制及超欠挖情况的分析与统计.

The construction setting out survey is carried out by establishing the rectangular coordinate system of the vertical section direction of the inclined shaft related to the slope.Compared with the conventional calculation of the slope distance and the calculation of the height difference,the scheme of setting out the inclined shaft has the advantages of simplicity,efficiency and directness in the field construction setting out and the processing of the interior data.At the same time,it is conducive to the site construction setting out and the drawing of cross-section diagram,as well as the analysis and statistics of over and under excavation.
