摘　　要：本文基于温排水物理模型相似关键条件,并研制了一套先进的加热温控系统和温度自动数据采集系统,建立了襄樊电厂二期工程温排水物理模型,试验从三维空间角度详细研究了电厂温排水对受纳水体-汉江的温升影响。通过电厂不同排水情况下排水口附近汉江水体表面温升、横断面温升分布和排水口轴线方向的温升分布的对比分析,推荐最优取排水口位置、布置型式等关键工程参数。Based on the similar laws of physical model of cooling water, the paper has developed a set of advanced heating-controlling and automatic temperature data collecting system, and then built up the cooling water physical model of the second stage of Xiangfan power plant project. Further in 3-D space, the experiment has studied the temperature influence by cool ing water from Xiangfan power plant to the receive water body-Han River. The best outfall and infall position and their arrangement style has been recommended through comparing and analyzing the Han River water surface temperature rising and cross section temperature rising and that in axes direction near the outfall under different condition.
