摘要
本文从微观的角度,分析了排海工程扩散管内海水入侵与冲洗的临界水力特点,并通过理论分析和物理模型试验的相互验证,得出了上述临界水力条件的判别关系式,提出了判别方法,并由此得到了深圳妈湾排海工程防止海水入侵的临界排放流量和出现海水入侵后的最小冲洗流量,为排海工程在非设计条件下的运行管理提供了依据。
In this paper,the hydraulic characteristics of the intrusin and purge of seawater in the diffuser were analyzed in the microcosmic view.Based on the illustration of the physical model experiment and theoretical analysis,the judgment formula of the hydraulic criterion was presented,and the critical discharges of the intrusion and purge of Shenzhen Ocean Outfalls were obtained.This can be provided a scientific basis for the operation management under the undesigned condition.
