摘要
针对实际工程中的发电引水隧洞运行的各种工况进行了水工模型试验研究 ,指明要获得良好的水流流态 ,过水建筑物各部位结构轮廓的造型应适应水流流线的收缩、流速及压强的变化 ;为使引水隧洞在各级引水流量下能安全可靠地运行 。
Through a series of hydraulic model tests for researching actual power tunnel operation,a conclusion is reached that in order to get a better flow pattern the profile of the wate carrying structure should be adapted to the variation of water streamline shrinkage,flow velocity and pressure intensity.The configuration and dimension of the kinetic energy dissipator should be selected carefully to make the water tunnel safe and reliable at different levels of diversion dischage.
