松滋河口门崩岸调查分析

Investigation and Analysis of Songzi River Outlet Caving Bank

摘要: 近年来，三峡水库运行后导致松滋河口门发生了较大规模崩岸，使本河段河床处于不稳定状态。本文利用水力学及河床演变学基本原理，结合实际调查勘测资料，分析了崩岸原因与发展趋势；论述了崩岸的危害，特别是对荆江防洪和江湖关系变化产生不利影响，提出了治理崩岸的措施。

Abstract: The Songzi River outlet has come up with a large scale of caved banks in recent years which led to un-steady state of the riverbed section. Using the basic hydraulic principle and riverbed evolution theory, the reasons and its development trend of the shore-collapse were investigated by actual survey on site and analyzed. The elaborated dangers of shore-collapse and the adverse effects on Jingjiang flood prevention and change of the relation between rivers and lakes were also discussed. The relative measures for managing these caved banks are proposed.
