摘　　要：针对长江下游感潮河段已建或拟建火电厂,在取排水口工程河段水文、地形地貌、泥沙特征、原型观测和物理试验研究成果的基础上,论述了取排水口的布置特点,分析了温升分布特征及取水温升。结果表明,长江下游感潮河段火电厂取排水口布置首先取决于厂址的选择,宜采用上取下排、远取近排、深取浅排的布置方式。Based on analysis of the hydrological, landform, and sediment characteristics and results of prototype observation and physical experiments at thermal plants having been built or to be built on tidal reaches of lower Yangtze River, the layout of water intakes and outlets was discussed, and the characteristics of temperature rise distribution at water intakes were analyzed. The result shows that the layout of water intakes and outlets should be determined mainly dependent on the sites of thermal plants, and that the layout patterns, such as upper reach water intake and lower reach water discharge, far distance water intake and short distance water discharge, and deep layer water intake and shallow layer water discharge are suitable for such projects.
