中文摘要:
      针对我国第一条30万吨级人工航道的扩建,从现状航道通航饱和度、核心港区船舶流量上升趋势、船舶大型化及靠泊需求等方面对航道扩建必要性进行阐述,通过对延长航道乘潮历时与航道通航能力的适应性分析,合理确定航道扩建规模和方案,对航道扩建后的水流条件改善、回淤、尺度模拟、船舶进槽和靠泊时机的匹配性等扩建效果进行系统研究,提出在现有航道基础上增深至-23.5 m、拓宽至440 m的扩建方案,通航效果良好,可满足到港船舶安全过槽及一潮靠泊的通航需求。
英文摘要:
      Aiming at the expansion of the first 300,000 DWT artificial channel in China,this paper expounds on the necessity of channel expansion from the aspects of navigation saturation,increasing trend of ship flow in core port area,upsizing of ships,and berthing demand,etc. Based on the analysis of the adaptability of extending the duration of tide and navigation capacity of the extended channel,the expansion scale and scheme of the channel are determined,and the effects of channel expansion,such as the improvement of flow conditions,sediment siltation,channel scale simulation,and the matching of the ships entering channel and berthing wharf time,are systematically studied. The proposed expansion scheme of deepening to -23.5 m and widening to 440 m is reasonable and has a good navigation effect,the expansion scheme can meet the navigation requirements of ships’ safe passing through the channel and berthing at one tide.
