摘　　要：根据水工模型试验成果 ,分析了三峡工程泄洪时坝下游引航道和两坝间河段 (三峡至葛洲坝 )的非恒定波流运动特性 ,结合遥控自航船模试验对两坝间的通航水流条件进行了分析评价 ,并提出了提高通航流量标准。Based on the results of hydraulic model test and remote control ship model, the unsteady flow characteristics in the downstream approach channel and the reaches from Three Gorges Project to Gezhouba Project and navigation conditions in these reaches during the TGP flood discharge are analyzed.The measures of raising navigation discharge level and improving navigation conditions are given.
