工程测量中如何提高后方交会测量精度
How to Improve the Accuracy of Rear Intersection Measurement in Engineering Surveying
摘要
Abstract
This paper takes the use of three known points for rear intersection,which is frequently used in measurement sites,as an example to explore the principle,calculation formula,and influencing factors of measuring the accuracy of the coordinates of the target point through rear intersection.It proposes reasonable measures to improve accuracy based on the factors affecting the accuracy of the coordinates of the fixed point and on-site measurement experience,and verifies them with practical engineering examples.By comparison,it can be seen that the coordinate accuracy measured by the rear intersection method can meet the accuracy requirements specified in engineering surveying standards,and can quickly solve practical engineering problems.关键词
