摘　　要：建筑物轴线的放样主要是计算出各轴线的交点的坐标,然后通过全站仪极坐标放样的方法定出轴线交点的位置。由于建筑物坐标系和测量坐标系不同,应先通过坐标转换将建筑物轴线交点转换为测量指标,本文提出无需进行坐标转换,而是通过建立建筑方格网主轴线法线式直线方程,并以此推求出建筑物轴线的法线式直线方程,进而通过解方程组求得交点坐标。Setting out the main axis of the building is to calculate the coordinates of the intersection of the axis, and then setting out the total station to determine axes intersection point. As the building coordinate system is different from the measurement coordinate system, we should first convert axes intersection point to measurement index by coordinate conversion. The article creates normal linear equation of building grid and inquires out the building axis normal linear equation, then solves equations to obtain the intersection coordinates.
