漫湾水电站水库淤积测量自动化实现

Realization of Automatic Accretion Survey of Manwan Hydropower Station

随着GPS—RTK技术的出现，以及计算机技术的高速发展，使得平面定位技术实现了高精度、自动化、数字化、实时化，而随着测深技术的数字化、自动化，为水下地形测量的数字化、自动化提供了基础，为水利工程水文勘测提供了先进的手段。本文就全自动数字导航水下地形测量系统的组成、工作原理及作业方法在漫湾水电站水库淤积测量工程中的应用进行了介绍，并根据工程实际，对其测量精度、误差来源进行了分析。

With the appearance of GPS-RTK technology and the quick development of computer technologies, the plane positioning technology becomes highly precise, automatic, digital and real-time. The digitization and automation of deep sounding technology lay a foundation for that of underwater cartographic surveying and promises advanced means for the hydrologic exploration of hydraulic works. This paper makes introduction to the application of automatic digital navigation based underwater cartographic surveying system＇s structure, working principle and operating method in the accretion surveying of the reservoir of Manwan Hydropower Station and analyzes the accretion surveying＇s accuracy and error in accordance with the project＇s practical situation.
