GPS-RTK Measurement Technology in Water Conservancy Projects Application in As-built Inspection

分析了GPS-RTK技术在水利工程竣工测量中的优势。为了弥补GPS-RTK在高程测量中精度不足的问题,采用高程拟合方法,通过计算数据点的高程异常值,得到数据点在正常高系统下的高程值,从而提高检测的精度,满足水利工程测量的需求。根据实际竣工工程项目研究区的地形地势、检测要求选择适合的拟合方法,通过实验获取了更高精度的数据,验证了高程拟合方法在水利工程竣工检测中的可行性。

This article analyzes the advantages and challenges of GPS-RTK technology in the completion measurement of water conservancy projects,and proposes an improved detection method.In order to make up for the lack of accuracy of GPS-RTK in elevation measurement,the elevation fitting method is used to calculate the elevation anomalies of the data points to obtain the elevation values of the data points under the normal high system,thereby improving the detection accuracy and meeting the needs of water conservancy projects.In order to demonstrate the feasibility of the method proposed in this article,it was validated in actual engineering completion projects,and suitable fitting methods were selected based on the terrain and detection requirements of the study area.Higher accuracy data was obtained through experiments to prove the feasibility of this method in the completion inspection of water conservancy projects.
