The main work is done with the help of model experiment. in the flood - relief experiment, the flood carrying capacity of spillway tunnel is checked. in the hydraulic experiment of the diversion power conduit system, the followings are studied : the flow condition and fluctuation in the surge chamber, the distribution of flow velocity before the rack in the surge shaft, the amplitude of stage in the quick gate bay etc. the test step, content and results of different proposals are introduced in details
本項優化試驗研究的目的主要在於，通過泄洪系統整體水力學試驗，校核泄洪洞的泄流能力；通過發電引水系統整體水力學試驗，研究調壓井內水流流態和水位波動情況、調壓井內攔污柵前流速分佈情況；確定快速閘門井內水位波動幅度；試驗確定壓力管道水擊壓力穿井系數以及泄洪洞弧形門處的水壓力。A brief introduction is described which indudes the state of the art of research and design about the trashracks of conventional and pumped - storage hydroelectric plants, the necessary to research the flow - induced vibration of the trashrack bar by use of hydro - elastricity similaymodel and the background of this study
對抽水蓄能泵站攔污柵流激振動的研究狀況、設計方法，本研究課題的背景和採用水彈性模型研究柵條流激振動的必要性作了簡要說明。According to the gravity - elasticity similar law the model scale of bai shan pumped - storage hydroelectric plants is taken as the trashrack bar is made of zinc, the relative errors between its practical density and elastic modulus and its proper values are - 7. 82 % and + 1. 43 %, respectively. by lvs measuring the velocity distribution ahead the trashrack bar and on the basis of the velocity distribution the working conditions of the pumped - stroage hydroelectric plant are controled. the dynamic strain of the trashrack bar induced by flow are measured using strain slips
選擇白山抽水蓄能泵站攔污柵水彈性模型的主要比尺為_ l = 3 、 _ e = 3 、 _ p = 1 ，柵條用鋅板加工而成，模型材料的實際密度和應有密度的相對差為- 7 . 82 ，模型材料的實際彈模和應有彈模的相對差為+ 1 . 43 ，用激光流速儀量測柵前流速分佈，並用流速分佈作為控制工況的依據，用應變儀量測柵條應變。Standard test methods for tensile strength characteristics of oil spill response boom
