嘉陵江草街航电枢纽施工导流明渠通航船模试验研究

为了配合草街航电枢纽工程的设计和施工,论证工程布置的合理性和可行性,按照试验要求制作了船模,并对有关工程的设计布置方案进行了优化和研究。分别根据水工模型比较方案和推荐方案,进行施工导流明渠及连接段的船模通航试验研究。根据船模试验最高安全限制的要求,结合相关水流条件的船模通航试验研究,对2个布置方案冲淤前后的试验结果进行分析,比较各方案通航条件的优劣,给出了通航推荐方案及建议。

Research on navigable ship model experiment of Caojie Hydro-junction open diversion channel during construction period in Jialing River

In order to demonstrate the availability and feasibility of the arrangement scheme of CaoJie Hydro-junction,the ship model was made on the basis of experimental requirements,and the related arrangement schemes were studied and optimized.The navigable ship model experiments of the open diversion channel during construction period and the connecting section were conducted based on the alternative scheme and recommended scheme.According to the highest security restrictions of ship model test and experimental study under the relevant flow conditions,the test results of the two schemes were analyzed,and the advantages and disadvantages of each scheme were compared.Finally,the recommended proposal and suggestion were put forward.
