GPS测量技术在瀑布沟水库断面测量中的应用

GPS Measuring Technique for Section Survey in Pubugou Reservoir

为提高工作效率,降低劳动强度,满足高水深、大跨度水库泥沙淤积测量的要求,通过全球定位系统联合回声测深仪对瀑布沟水库进行了断面测量。文中介绍了该方法的测量原理及特点,并将其测量成果与传统方法进行了对比分析。结果表明,该方法的测量精度满足断面测量的要求,且提高了自动化应用水平。

In order to improve efficiency and reduce labor intensity,and meet requirements of high water depth and long span reservoir sedimentation measurement,the sedimentation cross-section measurement on Pubugou reservoir is carried out through GPS technology combined with echo-sounder.The measure principle and characteristics of the method is introduced.And its measurement results were compared with that of traditional methods,which shows that measurement accuracy of the method meets the requirements of cross-section measurements,and it also improves automation level of measurement.
