一种边坡挡土墙位移测量误差分析方法

An Error Analysis Method for Displacement Measurement of Slope Retaining Wall

摘要: 由于测量工程的特性，在变形观测时，其测量数据必然存在一定的误差。因此，在变形监测时需要采取一定的措施，控制误差，使误差在允许范围内。本文通过在边坡挡土墙布设关键监测点，在实施边坡工程挡土墙变形测量，利用变形相关性计算公式，对关键测点的监测数据进行相关性分析，以校验监测数据的误差偏移程度。利用关键点监测数据的相关性，可对监测数据的准确性进行快速判断，减少内业的工作量，提高内业的工作效率。

Abstract: Due to the characteristics of surveying engineering, there must be some errors in the data of deformation observation. Therefore, some measures should be taken to control the error in deformation monitoring, so that the error is within the allowable range. In this paper, the key monitoring points are laid out in the slope retaining wall, and the deformation measurement of the slope engineering retaining wall is carried out. The correlation analysis of the monitoring data of the key measuring points is carried out by using the deformation correlation formula to check the error deviation of the monitoring data. By using the correlation of the monitoring data of key points, the accuracy of the monitoring data can be quickly judged, the workload of the indoor operation can be reduced, and the work efficiency of the indoor operation can be improved.
