对于温度成层型水库，水电站进水口分层取水方式正逐步被采用，目的是尽量取用水库不同层水体，减轻下泄低温水对下游河段环境的负面影响。目前缺乏分层取水流动规律及取水效果的研究。以糯扎渡水电站进水口叠梁门分层取水方案为例，通过数值模拟方法，研究叠梁门分层取水的流动规律，在水库水温分布已知的条件下，探讨叠梁门取水控制下泄水温的效果。研究成果对水电站进水口分层取水设计及运行管理具有重要意义。

In thermally stratified reservoirs, in order to withdraw water from different layers and alleviate the negative effect of lower-temperature water released on the environment of downstream reach, a multi-level intake structure (MLIS) was adopted in hydropower station. Considering the lack of the study on flow patterns and effect of multi-level withdrawal, based on the multi-level intake with stop logs gate in Nuozhadu hydropower station, the hydraulic behavior of the intake was studied by using a 3D turbulent model, and with the knowledge of water temperature distribution, the effect of the intake was also researched. The results are greatly meaningful for the design of multi-level intake structures of a hydropower station.
