RTK及测深仪联合水下地形测量中的应用

摘要

In order to check the topography under water given by design drawing and measure earth quantity of late period, the RTK depth sounder is used in the topography survey under water. The principle （no tide law）of topography survey under water with RTK depth sounder is introduced. The method of survey, issues which should be paid attention to and its superiority are stated in the light of actual situation of an engineering.%摘要：为复核设计图纸给定的水下地形，并为计量后期吹泥量，在水下地形测量中使用RTK及测深仪。介绍RTK与测深仪联合使用测量水下地形图（无验潮法）的原理，结合工程实际情况，说明RTK与测深仪联合使用测量水下地形图的方法、使用中应注意的问题及其优越性。
