摘要
阐述了测量特殊点位高程的几种方法，提出了垂直面内建立基线的同向测量法，推导了该方法的计算公式和误差公式，分析了影响高程测量精度的因素。以误差分析的结论为依据，进行了实验验证。将垂直面内建立基线的同向测量法和三角高程测量得到的目标点高程进行比较，差值很小，表明该方法可以达到一定的精度，具有较强的实用性。
Several special point elevation measurement methods are presented and the same - direction method which establishes a baseline in vertical plane is proposed. The calculation formula and error formula of the method are derived, and factors affecting the precision of elevation measurement are analyzed, Based on the result of error analysis, the method is validated by experiment. Besides, there is a minor difference when comparing the elevation of target point using this method with the one using trigonometric leveling method. The result indicates that the method can achieve a certain level of precision and possesses a good practicability.
