黄骅港整治工程前,航道内大风回淤后有大段的强淤难挖段。首先分析了黄骅港整治工程前航道内回淤土难挖段的特点,又以大量实测为依据,分析了黄骅港整治工程后航道内回淤土的各项特性、指标的变化,阐述了黄骅港整治工程对航道回淤土可挖性的影响,分析原因认为:黄骅港整治工程掩护了原有强淤难挖段,改善了被掩护段的颗粒组成,提高了回淤土可挖性,航道淤积重心外移,使疏浚力量重分配,提高了疏浚效率,增加了航道水深。 相似文献

本文基于连云港港15万吨级航道2005年11月至2008年9月疏浚施工过程中的大量现场观测资料,进行了施工期泥沙回淤特征分析以及施工期泥沙回淤风险识别。研究表明,连云港航道施工期回淤与自然回淤特征基本一致,但是施工期回淤受大风影响更为显著,大风与设计分摊不足是连云港航道疏浚施工回淤的主要风险因子。 相似文献

针对连云港港区25万吨级进港航道回淤总量小于15万吨级的现象,从航道回淤实测资料、工程前后水动力环境等入手,借助于潮流数学模型,研究了该现象产生的原因。研究结果表明:疏浚工程和环抱式防波堤工程均会对进港航道的回淤产生一定的影响,但防波堤的影响起主要作用。疏浚工程导致航道流速以减弱为主,因而使得航道回淤略有增加;而环抱式防波堤工程,将使口门附近流速显著增加,从而导致进港航道回淤大幅减小。此外,环抱式防波堤的掩护作用,在很大程度上阻挡了泥沙进入港区,从而使口内航道段回淤也大幅降低。 相似文献
