| 摘 要： | 利用传统三角高程原理和方法推导一种全站仪三角高程测量新方法计算公式。该方法的优点是在观测的过程中不需要量测仪器和棱镜高,从而达到提高精度的目的;并利用误差传播定律进行精度估算和分析,通过与《工程测量规范》中相应的水准闭合差比较,得出在一定条件下该方法可以代替三、四等水准测量。此方法用在施工测量中可以大大地提高工作效率和缩短工程工期。

| Abstract: | It deduces the calculative formula about a new method of triangular elevation by measuring with traditional triangulated height of principle and means.The advantages of the method do not measure the height of instrument and prism during the measuring,so that the accuray can be improved.It analyzes the precision of the method by law of propagation of errors.Compared with relevant error of closure in leveling of Code for Engineering Surveying,it draws a conclusion that the new method can replace 3 and 4 grade traditional of levering measuring.The new method will greatly improve the efficiency of professional and shorten the duration of measurement. |
