摘　　要：针对大藤峡水利枢纽因在项目建议书和工可阶段运行方式发生变化而导致枢纽上游航道需整治滩险数量大幅增加的问题,对2种运行方式下的最低通航水位和一期蓄水前后施工水位进行对比分析,得出最低通航水位和开挖引起的下降值对航道设计方案及投资的影响,以及大藤峡一期蓄水前后施工水位成果。结论为库区航道整治方案受枢纽调度运行方式影响大,在设计时应重点分析调度运行方式对设计水位和设计方案的影响,结合枢纽蓄水计划,在蓄水前适当开展水上炸礁作业以控制投资。In view of the substantial increase of beach risks needing regulation in the upstream channel of the Datengxia hydro-junction due to the change of the operation mode of the hydro-junction in the project proposal and feasibility study stage,we analyze comparatively the lowest navigable stage under the two operation modes and the construction water level before and after the first-stage impoundment,and obtain the lowest navigable stage and the decline caused by excavation,the influence on the channel design scheme and investment,and the construction water level results before and after the first impoundment of Datengxia.The conclusion is that the channel regulation scheme in the reservoir area is greatly affected by the operation mode of the hydro-junction.In the design,the influence of dispatching operation mode on the design water level and design scheme should be analyzed emphatically.Combined with the water storage plan of the hydro-junction,the land reef blasting operation should be reasonably arranged before the water storage to control the investment.
