摘要
研究了利用全站仪测量淤地坝的方法.测站的选择要充分研究淤地坝周围的地形,尽可能利用一个测站完成坝体测量;采用三点校正法保证支导线测量图根点的精度;测量坐标系采用独立平面坐标系,高程采用淤地坝原设计高程;测量中使用全站仪免棱镜模式以提高观测效率;采用均匀布点和地性线集中布点的方法采集坐标点;内业制图通过添删高程点修改三角网,生成符合实际的地形图.
The thesis introduces methods about how to measure silt storage dams with the total-station instrument. Specifically, they are： the topography around the dam should be taken into consideration to select station settings and complete dam measurement in one survey station as far as possible; to ensure the precision of turning points, precise measurement and three-point calibration should be used; the measuring of coordinate system should be done with independent coordinate system, and el- evation with the original design of dam elevation measurement; the non-prism technique can be used to increase efficiency of observation; coordinate point can be collected by uniform distribution and line distribution; modified triangle network can be achieved by adding or deleting elevational point within the drawing industry, then an actual terrain map will be generated.
