【摘要】 随着改革开放的进展，闽江两岸的经济也得到了飞速的发展。然而闽江流域内河网密布，在台风雨季，径流量很大，时有山洪爆发。同时，由于人类活动、以及自然问题等诸多原因，导致沿江两岸接二连三发生堤坝、桥梁、码头等建筑物的崩塌和破坏，严重影响了福州市的经济发展和两岸人民的正常生活。为此，急需对闽江竹岐至科贡、文山里河段进行全面规划和综合整治。使得在经济持续高速发展的同时，改善闽江自然条件，提高防洪排涝、通航及取排水等能力，确保福州市防洪安全。 本文将在已有的航道整治经验的基础上，结合闽江大量现场实测资料、分析资料及过去的研究成果，运用物理模型对闽江竹岐至文山里、科贡河段进行治导线研究，找出推荐方案。为了解决物模下边界分流口不易控制问题，本文同时采用数学模型进行更大范围即竹岐至白岩潭计算，将文山里、科贡水位、分流比提供给物理模型。同时，将方案计算结果与物理模型相互验证。更多还原

【Abstract】 with the rapid development of innovation and opening ,The economy of Minjiang River area developed very fast. But in Minjiang River drainage area, river networks are densely covered, influx are great and mountain floods happen casually in tycoon season. At the same time, as a result of human activity and natural matters etc, the falling and breakage of dams, bridges, docks happened frequently, which influence the economy development of Fuzhou and people’s living in this area. For this reason, the comprehensive layout and integrated regulation of the area from Zhuqi to Kegong in Minjiang River are urgently needed, these measures will improve the natural conditions of Minjiang River and enhance the ability of flood controlling, shipping and drainage to insure the security of Fuzhou.Based on the experience of existing waterway regulation, using a great deal of field data, analytic data and existing research findings, the ragulate lead on the area from Zhuqi to Kegong in Minjiang River are studied by using physical models and schemes are recommended in this thesis. Additionally, the feasibility of schemes are further proved. In order to solute the problem of diffluence mouth’s uppityness in the underneath boundary in physics model, the dissertation adopts numerical model to calculate the area from Zhuqi to Baiyantan ,and offer the physics model and the water level of Wenshanli and Kegong and the diffluence rate .at the same time, the dissertation compare the result between physics model and numerical model in different project.更多还原
