摘要：论述小龙潭水利工程GPS控制网和全站仪三角高程测量的布设方法,重点分析GPS控制网和高程测量的计算精度,以及在测量过程中应遵守的有关测量的限差要求;同时证实了在山区水利工程中利用GPS建立控制网的高效可靠性,检验了全站仪三角高程测量可以代替四等水准测量的规定。
This paper discusses the GPS control network layout and the way of trigonometric leveling with distance measurement by the total station .And it focuses its attention on analyzing the accuracy calculated of GPS control networks and height survey .The rules for relevant tolerance of specifications must be complied within the process of measuring .It also confirms the reliability of the GPS control networks for water resources engineering in mountainous areas .It verifies the rule that the fourth-order leveling can be replaced by trigonometric leveling with total station distance measurement .
