摘　　要：为了方便利用测量控制点作为测设依据进行线路工程施工放样,需要将施工坐标转换为测量坐标。本文利用坐标转换法,结合工程实例,分别对路线左、右转两种情况下不同走向的综合曲线中边桩坐标计算进行详细分析比较,推导出综合曲线上任意点的中边桩测量坐标计算通用公式。经实践验证,使用该通用公式计算得出的结果准确可靠。为测绘类和相关专业的初学者及工程实践一线技术人员提供了简单直观、浅显易懂的综合曲线中边桩坐标计算的理论学习参考和工程实践应用依据。In order to facilitate the use of the measurement control point as the measurement basis of the line engineering construction,it is necessary to convert the construction coordinates into the measurement coordinates.In this paper,the coordinate transformation method and engineering examples were used to compare the coordinate calculation of the side piles in comprehensive curves with different directions,and the general formula for the measurement coordinate calculation of the middle side piles at any point on the comprehensive curve was derived.Through practice,the results calculated using this general formula are accurate and reliable.For beginners in surveying and mapping and related majors and front-line technicians of engineering practice,it provides a simple,intuitive,and easy-to-understand theoretical learning reference of the coordinate calculation of side piles in comprehensive curves and the application basis of engineering practice.
