GPS在水利工程中的应用概况及发展趋势

Overview and Developmental Trend of the Application of GPS in Water Conservancy Engineering

水利工程是国家的经济命脉,提高其工作效率、保障其安全运营是头等大事。全球定位系统GPS(Global Positioning System)以其连续、实时、高精度、全天候测量和自动化程度高等优点,在工程及灾害监测中的应用越来越广泛。然而,目前GPS在水利工程方面的应用也存在不足和局限性。首先对GPS技术用于水利工程的现状及其特点进行总结,然后对目前GPS用于水利工程及变形监测的模式、数据处理方法及其存在的问题作一一介绍和分析,最后探讨GPS技术的发展趋势。

Water conservancy is vitals of national economy, and how to improve its work efficiency and ensure its safe running is the most important thing. Global Positioning System（GPS） has made a strong impact on many aspects of all kind of engineering and prediction in disaster due to its 24 hours availability, real - time, high precision, operability under all weather conditions and automation. It is more and more widely used in engineering and hazard monitoring. In this paper, first of all, the present situation and features of the applications of GPS technologies in water conservancy are summarized. Then the deformation monitoring model, data processing method and limitations of the applications of GPS in water conser- vancy are introduced and analysed. Last but not least the development trend of GPS technology.
