摘要
湖南澧水武圣宫滩位于淞虎航线53 km航道内,是湖南省水路运输体系的重要一环,为提高其通航标准以及航运价值,对该处航道进行改道处理。着重分析河段的演变趋势和碍航特性,提出澧水武圣宫滩航道的改道方案。通过数值模拟试验,研究航道改道工程实施后,河段通航条件的变化情况,分析不同来流条件下及最低通航水位时的参数变化趋势,以及开挖航道的稳定性。数值模拟试验结果表明:方案实施后澧水武圣宫滩左汊开挖区水流条件及航道稳定性满足需要,河段航道改道在技术上可行,为类似险滩的治理提供可靠的理论依据。
Hunan Lishui Wushenggong beach is located in the 53 km channel of Songhu route,which is an important part of the waterway transportation system of Hunan province,and the waterway is rerouted improve its navigation standards and improve its shipping value.The paper focuses on the comprehensive analysis of the evolution trend and navigation characteristics of the study river section,and proposes the diversion scheme of Lishui Wushenggong beach waterway.After the implementation of the channel diversion,the paper studies the changes of navigation conditions of the river section,the changes of relevant parameters under different flow conditions and the lowest navigable water level,analyses the stability of the excavated channel by numerical simulation model test.The model test results show that after the implementation of the scheme,the water flow conditions and channel stability of the excavation area of Lishui Wushenggong beach meet the needs,and it is technically feasible to study the channel diversion of the river section,which can provide a reliably theoretical basis for the treatment of similar dangerous beaches.
