从边坡沉降监测实际数据，可以看出若采用基于高边坡垂直特征线下双目标三角高程观测，在选择了有利的观测条件，并进行差分计算后，可以有效地消除或减弱大气折光带来的误差，相对没有进行动态改正的单向观测（按0．14的经验折光系数进行修正）结果，精度提高比较明显。本方法所需设备条件简单，具有测量方便、精度高和安全实用特点。

Seeing from monitoring data used for high slope settlement, it is known that the height error caused by atmospheric refraction could be effectively eliminated or decreased when the difference is carried out in the wake of the method of triangulated height surveying based on double - targets which are located on the same vertical line. Comparing to one - way observation without dynamic correction (just choose the 0.14 experience refraction coefficient as atmospheric refraction correction) in the same condition, the observation precision is raised obviously. Only with simple surveying equipment to acquire more accuracy height result, this method has the characteristic of prosperity of convenient surveying with safety and practicality.
