随着我国国民经济的发展,我国交通运输行业发展十分迅速,尤其是水路运输,以其独有的优势正在迎来新的发展机遇。要保证水运行业能够充分发挥作用,要建立起完善的水运工程控制网,与发达国家相比,我国水运工程控制网技术相对落后,采用的测量仪器十分传统,得到的数据不够精确,GPS技术并没有得到推广。笔者结合自身工作经验,对传统测量法的特点及GPS定位误差情况进行阐述分析,并结合实例对实际水运工程控制网中的应用进行了介绍。
With the development of our country’s national economy, the transportation industry in our country develops very rapidly, especially in the waterway transportation. With its unique advantages, new development opportunities are being ushered in. To ensure that the water transport industry can fully play its role, it is necessary to establish a complete control network for water transport projects. Compared with developed countries, the control network technology of China’s water transport projects is relatively backward. The measurement instruments used are quite traditional and the data obtained are not accurate enough. GPS technology Did not get promotion. The author combines his own work experience, the characteristics of the traditional measurement methods and GPS positioning error analysis and analysis of examples, and the actual use of water project control network is introduced.
