Abstract
In order to improve the accuracy and efficiency of railway engineering survey,a railway engineering survey technology scheme design integrating GPS-RTK technology is introduced.The survey area overview,GPS-RTK system composition,GPS control point layout scheme,automatic selection of control nodes in railway engineering elevation survey,establishment of plane and quadratic curve fitting models,data processing,and display of survey results are analyzed.At the same time,the steps for verifying survey results were proposed,including experimental preparation and analysis of survey result accuracy.The results indicate that this technical solution can improve the accuracy and efficiency of railway engineering surveying,providing strong technical support for the design,construction,and operation of railway engineering.关键词
