贵州荔波平林水电站水工模型研究

Research on Hydraulic Model of Pinglin Hydropower Station in Libo,Guizhou

采用正态整体模型,按重力相似设计原理建立荔波平林水电站水工物理模型。针对溢洪道运行的水力特性和体形结构进行试验研究,测试工程在洪水期运行是否满足泄洪要求,优化了左边孔左边墩与下游厂房外墙连接型式,增强了泄水建筑物的安全性和合理性,使泄洪流态更平顺,满足消能防冲要求。并根据可预见在原型上发生的不利水流现象,优化原有设计提出预防和控制措施。

In the arid regions of northern China ,the drought-resistant peas were exposed to water stress at the seedling stage, the plant height was higher, and the number of branehes was smaller than that of the eontrol. Water stress eould promote the growth of the main and lateral roots of the drought-resistant peas.After rehy- dration treatment, the plant height and branehing of peas ean produee a eompensatory effeet, whieh ean reduee the adverse effeets of water stress on the growth of main and lateral roots of dried peas.
