采用水深平均的ｋ－ε湍流数学模型，在三峡成库后不同时期修建和未修建防护堤的河道地形条件下，进行了中水（Ｑ长＝２８８００ｍ３／ｓ，Ｑ乌＝２０５４ｍ３／ｓ）流场的数值模拟，从流场的角度探讨了防护堤堤线优化问题。由于该河段的床面形态和平面形状均较复杂，因此这一研究的成功表明其可以方便地推广应用于其它类似的工程问题。
Based on the k-ε turbulence mathematical model of water depth and depth, the water flows (Q length = 28800m3 / s, Qwu = 2054m3 / s) were carried out under the channel topography of the Three Gorges constructed and un- Field numerical simulation, from the perspective of the flow field to discuss the embankment line protection optimization problem. The success of this study shows that it can be conveniently applied to other similar engineering problems because of the complicated bed shape and planar shape of the river section.
