【摘要】 常见的高边坡监测方法是在高边坡附近设立固定的观测基点对高边坡进行变形监测,但在市区内,由于通视条件和场地的限制,使得观测基点离高边坡比较近,容易受到高边坡变形的影响,从而影响观测数据的准确性。为了避免高边坡变形对固定观测基点的影响,提高观测精度,本文提出了全站仪自由设站坐标差分的观测方法,论述了该方法的原理、误差分析以及其在高边坡变形监测中的应用。更多还原

【Abstract】 The most common used method for safe monitor of high slope is to set a fixed observation point to monitor the transformation. But in urban area, due to restriction of the site and telecommunication conditions the transformation of high slope may have an impact to the fixed point and the result and the result we take from the point may be not correct. To avoid the impact and improve the accuracy, in this paper, a coordinate difference method to monitor the transformation of high slope with Total station actively is put forward and the principle, error analyses of this method are described and its application in safe monitor of high slope is introduced.更多还原
