摘要
在苏通GIL综合管廊工程中采用三角高程传递的方法完成了长江两岸长距离跨江的高程传递,其精度满足了国家二等水准测量的技术要求。同时采用改进的三角高程测量方法进行了测量实验验证了该方法在长距离跨江测量中运用的可行性;通过测量成果与GPS拟合高程结果比较,验证了跨江高程传递结果的可靠性。
In the Su-tong GIL integrated corridor project, the method of triangular elevation transfer is adopted to complete the transmission of the long distance across the Yangtze River, and the precision meets the technical requirement of the national second-order leveling. At the same time, the improved triangulation measurement method is used to validate the feasibility of the method in the long-distance river crossing survey. The reliability of the results is verified by comparing the measured results with the GPS fitting elevation results.
