长江中下游崩岸分布规律及窝崩的平面旋涡形成机制

基于遥感综合研究，论述了长江中下游条崩与窝崩的分布规律，在此基础上讨论了两类崩岸的形成机制，特别是对窝崩的平面旋涡形成机制进行了论述。窝崩是在特定岸段因平面旋涡的形成而发生的，通过流体力学的涡流理论分析，提出了用临界负压评价窝崩形成的原理与方法。

Exploration of distributed law of bank collapsing and plane eddy mechanism of arc collapsing along middle-lower Yangtze River

Based on remote sensing synthetic analysis, the distribution regularities of strip collapsing and arc collapsing along middle-lower Yangtze River are explored. The mechanisms of the two types of bank collapsing, especially the plane eddy mechanism of arc collapsing are discussed. It is considered that the occurrence of arc collapsing is resulted from the forming of whirlpools near some special shores. Using the eddy theory of hydrodynamics, the principles and the method by means of critical negative pressure to evaluate the occurrence of arc collapsing are suggested.
