摘要
长江口水域宽广、水动力条件和泥沙运移复杂、滩面物质易发生冲蚀,局部河势变化存在不确定性,必须制定严密的现场观测制度,掌握现场水沙地形变化,实施动态管理。文章介绍工程特点、现场观测安排的原则及技术应用等。保障了长江口深水航道治理工程的顺利建设及进入维护期后12.5 m深水航道的长远稳定运行。
The Yangtze estuary has a broad water area, complex morphology, and variable conditions of hydrodynamics and sediment, the material on the river bed is highly erodible and the local morphological change is uncertain. Systematic survey plans should be established and topographical change of water and sand in site should be mastered, and dynamic management has to be developed. The project characteristics, principles of survey organization and application of new technologies were intro duced in this paper. It guaranteed a successful channel regulation work and maintained the 12.5 m deep draft channel.
