| 摘 要： | 在悬高测量基本原理的基础上,文章探讨了一种适用于特殊情况下悬高测量的新方法——变动仪器高法,并推导出该方法的精度计算公式。利用该方法,通过实例计算,对其测量误差进行了分析;结果表明,该方法步骤简便,工作量小及效率高,并且很少受地形条件的限制,在一般情况下,观测精度可达到厘米级,能够满足一般工程测量的要求。

| Abstract: | On the basis of the basic principle of remote elevation measurement(REM),a new method of REM in some special situations,the method of measuring through changing the apparatus's height,is presented,and a formula of accuracy of REM by the method is deduced.An application case is given and the error analyzed.The results prove that the presented method is a high-efficient,easy-conducting and labor-saving method and the measurement is seldom restricted by topographic conditions.Generally,the accuracy of this method can reach the order of a centimeter which can meet the requirement of ordinary projects. |
