浅议东莞航道1︰2000水下地形测量工程实践经验

Discussion on Engineering Practical Experience of Underwater Topographic Survey in 1 2000 Scale on Dongguan Channel

本文以东莞市某航道水下地形测量为例,介绍了GPS—RTK配合测深仪技术在水下地形测量中的应用。依据项目特点,结合作者多年从事水下地形测量工作的经验,对创建国家级"文明样板航道"水下地形测量顺利实施提出了几点建议。

Taking the underwater topographic survey in 1 ： 2000 scale on Dongguan channel as an example, the author introduces the application of GPS-RTK in underwater topographic survey cooperating with depth sounder. Based on the Characteristic of Dongguan channel and engineering practical experience, the author putted some advices for underwater topographic survey on Dongguan channel, which as the model channel of china, that the quality control and project responsibility system are the important means ensuring the project trouble-free operation.
