摘要
研究测量机器人应用于黄土滑坡地质灾害监测时的精度和可靠性等问题,结合泾河南塬庙店黄土滑坡监测实例,采用移动式半自动变形监测作业方式进行外业观测,对实测数据进行计算,并将测量机器人的监测成果同位移计的结果对比。结果表明,测量机器人的实测平均平面点位中误差为±4.0 mm,垂直方向的平均高程中误差为±2.4 mm,满足工程测量规范设计要求,并且两种监测结果具有很好地一致性。基于测量机器人对黄土滑坡变形监测的成果精度高、可靠性强,完全可应用于高精度滑坡地质灾害监测。
In order to study the accuracy and reliability of geo-robot applied in loess landslide monitoring,the movable semi-automatic monitoring operation is adopted in the Miaodian loess landslide.Then the observed data are processed and analyzed.The statistical results indicate that the average mean square error(MSE)of horizontal direction is ±4.0 mm and the average MSE in the vertical direction is ±2.4 mm.The average MSE in both horizontal and vertical directions is within the tolerance.In the meantime,the results obtained from geo-robot and displacement meter are carefully compared as well.The monitoring results of the two methods have good consistency.Therefore,geo-robot can be completely used to the high-precision monitoring of landslide disasters due to its high accuracy and reliability.
