摘要
采用宽度平均的立面二维水温模型,通过分析支流和主库之间的相互影响,提出了支流与主库耦合的简化方法,建立了考虑支流影响的水库水温模型。在考虑有无支流影响的条件下,对水库水温分布、水库下泄水温和坝前垂向水温分布均作了比较,结果表明支流对水库水温分布有一定的影响,所建立支流与主库耦合的立面二维水温模型能够较好地反映存在支流影响的水库水温分布,预测水库水温分布比较合理。
Through analysis of the interaction between branches and reservoirs, a simplified method for coupling analysis of branches and reservoirs is put forward by use of the elevation width-averaged 2-D water temperature model, and a water temperature model for reservoirs with consideration of the influence of branches is established. The comparison of the result about reservoir water temperature distribution, discharge water temperature distribution, and temperature distribution in vertical direction in front of the dam obtained by the present model with those obtained without consideration of the influence of branches shows that branches have certain influence on reservoir water temperature, and that the established model is effective and reasonable for reflecting and predicting the reservoir water temperature distribution under influence of branches.
