摘要
与内陆地区相比,城市感潮河网在防洪排涝和水环境保护等方面面临较大压力,沿江水闸利用潮差进行内河引排水是提升感潮河网防洪排涝能力、改善水环境的有效途径,但临江工业的发展与感潮河网引排水容易形成矛盾。以南通农场闸闸口附近的惠生重工3#舾装码头新建工程为背景,采用数学模型研究舾装码头工程对感潮河网引排水的影响,提出一种将船舶概化成活动闸门的船舶阻水作用分析的等效处理方法,并验证其合理性。研究认为舾装码头工程口门拓宽疏浚措施对感潮河网排水排涝有利、对感潮河网引水不利,口门泊船对感潮河网引排水影响甚微。
Compared with inland areas,the urban tidal river network faces greater pressure in terms of flood and waterlog control and water environment protection.The use of tidal range for inland river diversion and drainage by the sluices along outer river is an effective way to enhance the flood control and drainage capacity of tidal river network and improve its water environment quality.However,the development of riverside industries along outer river is in contradiction with the water diversion and drainage of tidal river network.For arguing the new construction of Huisheng Heavy Industry 3#Outfitting Wharf near the gate of Nantong Farm Sluice,in this research,mathematical models were used to investigate the influence of the outfitting wharf project on the diversion and drainage of tidal river network,and a generalization of ship into movable gate was proposed.The equivalent treatment method for the analysis of the water blocking effect of the ship and its rationality were verified.It is concluded that the widening of the dredging measures at the entrance of the outfitting wharf project are beneficial to the drainage of the tidal river network,but are not good for the water diversion of the tidal river network.Ship mooring at the entrance has little effect on the diversion and drainage of the tidal river network.
