| 摘 要： | 针对通航建筑物下游检修水位确定的问题,通过工程类比方法,对坝址天然流量、入库流量、调峰流量、最大发电流量、下游梯级回水顶托和上游梯级群建成后对入库流量的影响等因素进行综合分析,认为宜选择对电站出力影响最小的下游水位作为通航建筑物的下游检修水位。

| Abstract: | For determining the downstream maintenance water level of large navigation structures,we adopt the engineering analogy method to analyze the influential factors such as the natural reservoir inflow,peak regulation flow,backwater effect of the downstream cascade,as well as the influence to the reservoir inflow on the upstream cascades after construction.The result is obtained that the water level which has the minimum impact on the output of the powerhouse should be chosen as the maintenance water level of the navigation structures. |

| Keywords: | navigation structure maintenance water level maintenance time instantaneous maximum flow |
