四、几点体会 通过以上几种弯道型浅滩特性分析、模型试验研究和工程实践经验,概括起来有如下几点体会和认识。 (一)应根据滩险碍航的主要原因,采取整治措施。川江弯道型浅滩不论是何种类别的滩险,其共同特性是面流形成扫弯滩势,弯道环流和岩咀下降水流共同作用下,底流常在突咀的对岸形成强泡,并加强其上段浅碛处的回流强度。泡水是种上升水流,能量 Fourth, a few experiences Through the above several curved channel characteristics analysis, model test research and engineering practice, summed up the following experience and understanding. (A) Measures should be taken according to the main reason for the inshore accident. Regardless of the type of beach, the common features of the rivers in the bend of the Chuanjiang River are that the surface currents form sweep swells, the circulation of the curves and the downward flow of the rock cores, and the underflow often forms strong bubbles on the opposite bank of the tuyere Strengthen the upper part of the shallow moraine reflux intensity. Bubble water is a kind of rising water flow, energy
