1研究成果表明,长江中下游各河段泄流能力在三峡工程运用后不同时期发生不同程度的变化.
2三峡水库蓄水运用后一段时期内,上游河段泄流能力的增加大于下游河段,会增加下游河段的防洪压力,遇1954年洪水长江中下游超额洪量仍然巨大.
3通过大湖演进数学模型进一步研究了河道冲刷导致的上下游河道冲刷不平衡可能引起的超额洪量的转移及其超额洪量的时空分布,加之河道冲刷对堤防安全及河势稳定产生影响.
4从适当调整主要站防洪调度运行水位、三峡水库与上游控制性水库联合调度和河道治理等方面,探讨了三峡工程运用后对长江中下游防洪影响的响应措施.

Research results indicate that the middle and lower reaches of the Yangtze River discharge capacity after the operation of the Three Georges Project occurred in varying degrees at different times,after the time of the operation of the Three Georges,the discharge capacity increase of the upper reaches more than the lower reaches,it can increase the flood control press of the lower reaches,the mid-low reach of the Yangtze River’s excess flood is still huge in 1954 flood.Get across the great lake wave advance numeric model deeply research the transfer and space-time distributing of the excess flood be likely to the reach erode bring on the imbalance of the upper and lower reach erode,and it influence the dike safe and the stabilization of river circumstances.On the way of propriety adjust mostly stations’ flood control and attemper,run water level,the Three Georges and the upper reach reservoir combine control and reach father,discuss the response measure of the flood control influence in mid-low reach of the Yangtze River after the operation of the Three Georges Project.
