【摘要】：使用全站仪对滑坡监测是一种简捷有效的方法,本文对该方法做了简要介绍,以一个滑坡监测点某一期为例,分析了其水平位移点位中误差与垂直位移高程中误差的精度情况。滑坡监测点水平位移主滑方向精度主要受测站点与监测点的连线和主滑反方向夹角、水平角测量精度、测距精度、测站点与监测点的距离等影响。垂直位移高程精度主要受垂直角测量精度、测站点与监测点的距离、测距精度、仪器高测量精度影响,分别推导了误差公式,并进行了量化计算,验证了各项因素的影响程度,可为相似工程提供有益参考。
[Abstract]:The use of total station is a simple and effective method for landslide monitoring. This paper briefly introduces this method. Taking a landslide monitoring point for an example, the accuracy of the errors in horizontal displacement and vertical displacement elevation is analyzed. The accuracy of the main direction of horizontal displacement of landslide monitoring points is mainly affected by the connection between the station and the monitoring point and the angle between the main slip and the reverse direction, the measuring accuracy of horizontal angle, the accuracy of ranging, the distance between the site and the monitoring point, and so on. The accuracy of vertical displacement elevation is mainly affected by the accuracy of vertical angle measurement, the distance between the station and the monitoring point, the ranging accuracy and the measuring accuracy of the instrument. The error formulas are derived, and the quantitative calculation is carried out to verify the influence degree of each factor. It can provide useful reference for similar engineering.
