| 摘 要： | 应用Mike21FM 2008对来宾电厂温排水的环境影响进行数值模拟，建立了以三角形/四边形混合网格为基础的地形文件，率定了模型参数(糙率和涡粘系数)，建立了水动力模型，开展了温排水的数值模拟预测，模拟2种工况(夏季90%枯水和全年90%枯水)条件下的温排水对河流水环境的影响过程，根据模型预测结果可以得出不同温升线包络的范围以及不同河流来水量情况下电厂温排水对河流水环境的影响程度. 提出把Mike21FM模型软件应用到环境影响评价领域的实现方法和应用过程，明确在环境影响评价过程中二维水域环境影响预测应该关注的重点，以及对原始数据资料的需求.

| Abstract: | A numerical model of thermal discharge from Laibin power plant was researched based on Mike21FM.A triangle/quadrilateral mixed mesh-based bathymetry was established.A calibration of the HD model was performed.A simulation and forecast of thermal discharge was done.The result of thermal discharge affecting Laibin River was simulated under two conditions of low water of 90% probability in summer and throughout the year.The range of the temperature rise could be concluded according to the simulation results.Th... |
