摘要: |
赣江龙头山枢纽已建Ⅲ级船闸一座,可通航1000t级船舶。2019年4月船闸试运行后,发现船闸安全通航流量较低,达不到原设计标准,影响船闸的通航安全和船舶过境效率。本文在资料分析和物理模型试验的基础上,分析了现状船闸通航水流条件及存在问题,剖析了其不达标原因,提出了一种新型的百叶窗式透空隔流堤措施以改善一线船闸通航水流条件,可有效提升最大安全通航流量,为已建船闸完善方案、预留二线船闸设计和今后运行管理提供科学依据,具有重要的工程实践意义,可为已建工程类似问题的解决提供新的技术途径。 |

Abstract: |
A three-level navigation lock was built at Longtoushan junction and operated since the April in 2019. But the design standard is not achieved and there is a real safety risk. On the base of data analysis and physical model test, the navigation flow condition was studied and the reasons was found. A new type measure was used and the safe discharge was enhanced obviously. The optimized scheme can help meet the design requirements and provide technical support for engineering design and operation and management in the future. The new measures can be popularized and applied in similar events. |
