摘要
跨水域高程传递是黄河口及沿海观测研究中的重要基础性工作,文中依据国家相关规范的要求,提出了利用改进的三角高程法进行跨水域高程传递。经过在实际工作中验证,测量精度能够满足国家二等水准所规定的精度,工作流程也得到了简化,作业效率得以提高。
The elevation transmission crossing water is an important basic work in the observation study of Yellow river estuary and the coastal. According to the requirements of relevant national codes, the improved triangle elevation method is used for elevation transmission crossing water. After test in practical work, the measurement accuracy could meet the accuracy requirements of the national second order leveling, along with the simplified work flow and the high operation efficiency.
