【摘要】 本文是针对当前水环境治理中普遍存在的泥沙淤积问题，结合国家863“十五”重大科技专项“镇江水环境质量改善及生态修复示范研究分项之二：湿地一内湖系统的水质改善、泥沙控制技术研究及示范工程”项目而开展的研究，主要内容包括：(1)总结国内外环境调水和水沙调控的研究成果，回顾前人对内江的整治和研究工作；(2)采用河工模型试验的方法，从水流流场、含沙量空间分布和泥沙淤积分布三个方面入手，对内江的水流泥沙运动特点以及存在的泥沙淤积问题进行分析；(3)通过对内江的水流泥沙运动特征进行深入地研究和分析，探索出采用控制工程进行水沙调控的方法，并针对控制工程的引水防沙效果进行了模拟研究；(4)在试验研究的基础上，采用优化规划的方法，对节制闸的运行调度方案进行研究，并且对节制闸的长效运行机制进行探讨。通过这些研究工作，最终找到既满足内江环境需水量要求的同时，又能减少长江的泥沙进入内江的合理调度方案，从而加快镇江市水环境治理的进程，并为其它地区的水沙调控研究提供有益的借鉴和帮助。更多还原

【Abstract】 This paper mainly deals with the sediment problems in water environment improvement. Theresearch background of this paper is the "Technical Study & Comprehensive Demonstrationon Improvement of Water Environment and Ecological Restoration in Zhenjiang", the majorspecial science & technology program of China during "the 10th Five-year Plan" period. Themain contents of this paper are as follows:(1)Aggregated domestic and foreign research results about water diversion and sedimentcontrol, recalled the research results of Neijiang River.(2)Through the physical model experiments, anaylzed water and sediment characteristics ofNeijiang River from three areas: the flow field, the concentration distribution and thesedimentation distribution.(3)Through the study on water and sediment characteristics, the author made the reasonableproposal and did relevant researches on the flow dynamic characteristics and siltationmechanism, in order to predict the sediment deposition after the project.(4)Based on the experimental results, the author used linear programming approach to theoperation of the regulator in scheduling options discussed, and study on the lasting runningprocess of the water level adjusting system.By means of the research measures of diverting water against sediment in Zhenjiang waterenvironment, it explores scientific, feasible means and channels of water sediment regulation,offers scientific basis to Zhenjiang water environment control. On the other hand, the researchprovides a reference about water environment control to others cities.更多还原
