摘　　要：溪洛渡下游30 km河道为限制通航区。为分析研究溪洛渡水电站下泄非恒定流对坝下限制性通航区的影响,对坝下游水流条件进行了原型观测。本文介绍了该河段沿程水位、波浪、流速流态监测技术方案及采用的新技术新方法,并对沿程水位变幅、波高、流速变化等进行了分析。结果可为研究溪洛渡下游限制性通航条件提供依据。The 30 km downstream of Xiluodu Hydropower Station is restricted navigation channel. In order to study the effect of unsteady flow on the restricted navigation area, the prototype observation of flow conditions downstream of the dam was carried out. The technical scheme and new methods of water level, wave and flow velocity monitoring were introduced. The amplitude variation of water level, wave height and velocity distribution along the channel was analyzed. The results can provide a basis for the study of restrictive navigation conditions downstream of Xiluodu Hydropower Station.
