晋江下游中芸洲二岛围固工程模型试验研究

Study on physical model test of Zhongyunzhou Second islands reclamation project in lower reach of Jinjiang River

基于潮汐河工模型试验,在分析晋江下游河段水流泥沙运动特征及河床演变的基础上,针对中芸洲二岛围固工程,系统地研究了二岛围固工程兴建后,防洪挡潮、围堤安全影响等问题,论证了工程建设对晋江下游河道行洪的影响,提出了围固工程平面布置的优化方案及河道治理措施的建议,为围固工程的设计与建设提供了科学依据。

In accordance with the tidal river model experiment,the effects of reclamation project in Zhong-yunzhou islands on flood control,tide protection and border dike safety were studied based on the analysis of flow and sediment transport characteristics and fluvial process.Meanwhile,an argumentation on the effect of draining flood in lower reach of Jinjiang River was given,and the optimization scheme as well as regulation measures were put forward,which can provide a scientific basis for the reclamation project.
