摘要
在对现有的截流难度指标进行分析后 ,从能量观点出发 ,探讨了龙口水流能量的各种表达式及其适用范围 ;根据抛投材料面积水力阻抗的概念 ,推导并提出了新的困难度指标——龙口水流能量面积平均值 ,并对其变化规律进行了研究 ;最后 。
After analyzing many existing difficulty indices of water closure,the paper discusses sorts of expressions of energy for water of closuring gap and their applicable range in view of energy. According to section area hydraulic resistance of closing materials, a new difficulty index is defined and recommended,that is energy for water of unit area, and its variation law is studied. Finally, for satisfying the need of field closure construction, we advance some guiding suggestions utilizing the new index.
