摘要
首次在潮汐河口采用局部正态物理模型研究了局部冲刷问题,结果表明:采用局部正态物理模型研究潮汐河口相关工程问题是可行的,试验水力条件的选择、模型边界的确定以及模型的整体变坡是将局部正态模型应用于潮汐河口的关键技术,提出了简便易行且效果良好的模型边界的确定方法,阐述了模型整体变坡的必要性及方法。
The local normal physical model is adopted to study the local scour （problems） on project in the tidal estuary for the first time. The results show that：1） It is feasible to apply the local normal physical model to study the engineering problems in the tidal estuary; 2） Choice of the test hydraulic conditions, determination of model boundary condition and entire variable slope of the model are the key techniques to apply the local normal physical model to the engineering problems in the tidal estuary;3） A simple and feasible method to determine model boundary condition is presented;4） The necessity and method of applying entire variable slope of the model are expounded.
