摘要
测量控制点精度关系工程建设质量。港口工程因地基稳定性差、地面变形大,造成控制点平面位移问题突出。结合港口工程案例,探讨基于BHCORS的工程控制点平面精度检核分析。采用坐标转换四参数法及实测基线比较法进行控制点内符合精度检核,采用BHCORS进行控制点外符合精度检核。对比分析结果表明,BHCORS成果精度高、现势性强,在港口工程建设中应用广泛。
The accuracy of control points is related to the quality of engineering construction.Due to the poor foundation stability and large ground deformation,the control point displacement problem is prominent in the port engineering.Based on the port engineering case,this paper probes into the plane precision analysis of engineering control points based on BHCORS.The method of coordinate conversion and baseline comparison are used to check the accuracy of the control points,and the BHCORS is used to check the accuracy of out-of-control points.The comparative analysis results show that BHCORS results are characterized by high precision and strong potential,and thus widely used in the port engineering.
