    摘要:

    厢廊急弯段河道河面较窄,弯顶航道转向角较大,入弯和出弯段主流流速较大,因此,针对船舶在上、下行无法通过厢廊急弯段的问题,进行急弯段航道整治的研究。采用正态定床物理模型试验的方法,并结合船模试验,通过分析沿程水位、航中线流速、航道横向流速及船模航行参数等指标,得出疏浚和调整航线相结合的较优整治方案。试验结果表明,采取凹岸和凸岸同时开挖的整治方案,在最大通航流量2 010 m3/s内可航水域范围,航线纵向及横向流速等通航水流条件均有所改善,船舶过弯航迹带减小,双向通航船舶可顺利通过厢廊急弯段。本研究可为类似急弯段航道整治研究提供借鉴。

    Abstract:

    The river channel of the sharp-bend compartment corridor is sharp bend and the river surface is narrow. The turning angle of the channel at the top of the curve is large,and the mainstream flow velocity at the turning section is high. To counter the problem that ships cannot pass the turning section of the corridor,we carry out a study on channel regulation at the sharp bend section. By the method of normal fixed bed physical model test and combining with the ship model test,we obtain the optimal regulation scheme which combines dredging with adjusting course based on the analysis of the indices such as the water level along the course,the velocity of the midcourse,the transverse velocity of the channel and the ship model sailing parameters. The experimental results show that,in the navigable water area with the maximum navigable flow of 2 010 m3/s,the navigable flow conditions,such as longitudinal and transverse velocity,are improved,the ship’s curved track zone is reduced,and the two-way navigable ships can pass through the sharp bend section of the corridor smoothly. This study can provide reference for the regulation of waterway in similar sharp curve sections.
