对于沉降监测，通常采用精密水准测量的方法。鉴于用传统几何水准的方法进行垂直位移监测存在效率低、受环境和地形因素影响大等问题，探讨用全站仪进行精密三角高程测量采监测垂直位移。为使三角高程测量的精度能够达到精密水准测量的精度，必须采取相应的措施．本文通过对中间法三角高程测量公式的精度估算及分析，研究了精密三角高程测量的误差来源及精度，并以及大量实测高差数据的统计，验证了用中间法代替二等水准测量的高可靠性和代替二等水准测量的基本条件。给出了站仪精密三角高程测量替代二等几何水准测量的条件、减弱误差的方法、优缺点及提高精度的措施等。
高手，谢谢了啊！！
The settlement monitoring, usually using the standard method of measuring precision. Given the standard of the traditional geometric method to monitor the vertical displacement of the existence of low efficiency, by environmental and topographical factors affecting such issues as to explore the use of total station for precision trigonometric leveling mining to monitor the vertical displacement. To make the accuracy of trigonometric leveling precision to achieve the standard of measurement precision, corresponding measures must be taken. Based on the intermediate trigonometric leveling method formula and analysis of the accuracy of estimates studied trigonometric leveling precision error sources and accuracy, and elevation data, as well as a large number of the measured statistics to verify the use of the middle class instead of the high standard of reliable measurement and second-class standard of measurement instead of the basic conditions. Points are given precise trigonometric l
