糯扎渡水电站进水口叠梁门分层取水研究

进水口分层取水是减免水电站发电下泄低温水体对下游生态环境不利影响的有效措施。结合澜沧江糯扎渡水电站进水口叠梁门分层取水的工程实例,通过水力学数值分析和水力学模型试验,叠梁闸门激流振动数值分析和模型试验等,叠梁门分层取水有效提高了下泄水体水温。糯扎渡水电站进水口叠梁门分层取水是可行和适用的,使水电站的建设与水生生态和谐发展。

Study on Multi-level Intake with Stoplog Gates of Nuozhadu Hydropower Station

The multi- level intake structure is an effective measure to reduce the adverse effect of released cold water on downstream living creatures especially fish. Taking Nuozhadu hydropower station as an example in this paper, the multi - level intake with stoplog gates of Nuozhadu Hydropower Station has proved feasible and applicable by conducting hydraulic numerical analysis and model test, stoplog gate flow- induced vibration numerical analysis and model test and analysis of released water temperature, and the multi - level intake with stoplog gates has effectively raised the tempera- ture of released water, thus the construction of the hydropower project and the aquatic ecological environment could devel- op in a harmonious way.
