葛洲坝大江船闸下游航道通航水流条件试验研究分析

Study on Navigation Condition of Dajiang Downstream Channel of Gezhouba Project

本文通过天然实测资料分析和模型试验 ,研究了葛洲坝大江下游航道的通航水流条件 ,指出了大江航道目前所存在的主要问题和枢纽调度运用对下游航道所产生的影响 ,同时预报了未来三峡工程蓄水运用后本河段可能产生的影响 ,为决策部门提供了科学依据。

The navigation condition of Dajiang downstream channel in Gezhouba Project has been studied by analyzing the field data and model test. The main problems for navigation existed in the project and the influence of the project operation on the downstream channel were also studied. In addition, the paper predicted the influence of the operation of the Three Gorges Project on the riverbed evolution and flow pattern in Dajiang downstream reach.
