摘要
基于晋江下游潮汐河工模型,根据晋江河口拦河闸坝运行目的以及晋江下游河道潮汐特征,概化了3种典型的运行方式。与上游不同流量进行组合,进行了不同运行方式下对比试验,观测分析了建闸后不同运行方式下潮位、流场的变化特征以及对河床变化形成的影响,并综合研究成果,提出合理的调度运行方式和改善措施。
Based on the tidal river model in the lower reaches of Jinjiang river,three typical operation manners were generalized according to the operation objective and flow characteristics near the barrier.Combining with different flow conditions in upstream Jinjiang river,the comparative tests under different operation manners were carried out.According to the test results,the variation characteristics of tidal level and flow field and the influence on river bed changes were analyzed in detail.Then the proper operation manner and improvement measures were also proposed in this paper.
