摘　　要：针对襄阳市东西轴线道路工程鱼梁洲段项目中沉管隧道两次跨越汉江,需建立高精度高程控制网,确保工程建设中沉管隧道精准对接,本文对跨河三角高程测量方法进行优化改进,探讨采用两套具有自动照准功能的精密全站仪和四套棱镜,采用双对向精密三角高程测量方法分别进行东汊和西汊高程的联测,研究结果表明:双对向跨河精密三角高程测量精度可达到二等水准测量精度,提高跨河高程测量作业效率,在类似跨河工程高精度高程测量中具有重要的参考和应用价值。As the immersed tube tunnel crosses the Han River twice in Yuliangzhou section of the East-West axis road project of Xiangyang City,it is necessary to establish a high-precision elevation control network to ensure the accurate connection of immersed tube tunnel in the construction of the project.This paper optimizes and improves the method of river-crossing triangulation elevation measurement.Two sets of precision total stations with automatic sighting function and four sets of prisms are used to measure the elevation of east and west branches of Han River respectively.The results show that:The method of double-sight river-crossing precision triangulation elevation measurement can reach the second-class leveling accuracy and improve the efficiency of the river-crossing elevation measurement,which has important reference and application value in the high-precision elevation measurement of similar river-crossing projects.
