刁口河河道及局部海域物理模型测控系统研究

Research on the Measurement and Control System for the Physical Model of the Diaokou River Channel and Local Sea Areas

淤积、延伸、摆动、改道是黄河口主要演变规律,黄河治理必须给黄河入海留有出路。刁口河作为备用流路、分洪通道、生态补水通道,其战略地位十分突出。因此,借助于物理模型试验手段开展刁口河相关重大问题研究至关重要。针对刁口河河道及局部海域实体物理模型,设计了一套潮汐模拟测控系统。该系统运行可靠、试验精度高,可实现上游流量、下游水位及流向等多边界耦合控制,为黄河治理提供技术支撑。

Siltation,extension,oscillation and diversion are the main evolution laws of the Yellow River Estuary,and the governance of the Yellow River must leave a way for the Yellow River to enter the sea.The Diaokou River,as a backup flow path,flood diversion channel and ecological water supplement channel,has a very promi-nent strategic position.Therefore,it is crucial to conduct research on major issues related to the Diaokou River with the help of physical model experiments.This article designs a tidal simulation and measurement system for the physical model of the Diaokou River channel and local sea areas.With reliable operation and high experimental ac-curacy,the system can achieve the multi-boundary coupling control of upstream flow,and the downstream water level and flow direction,which provides technical support for the governance of the Yellow River.
