摘要
Abstract
In order to study the water-intaking effect of the multi-level intake with stoplog gate for Fengman Hydropower Station Reconstruction Project,the physical model test and the numerical simulative analysis on water temperature are carried out.The study result shows that the expected effect can not be obtained from the the multi-level intake with stoplog gate;i.e.on the one hand,the distance between the original dam and the new dam is only 120 m and the remaining part of the original dam forms a prepositive retaining wall,which has a impact on the temperature distribution between both the dams and leads to a large decrease of the temperature difference between the surface and the bottom,and thus restricts the operation effect of the stoplog gate;on the other hand,due to the distance of 120 m between the original dam and the new dam,when the operation of the hydropower station,only a quite less impact is there on the thermal flux at the gap of the original dam,that is to say,the existence of the original dam forms a prepositive retaining wall that actually plays the role of a stoplog gate.Based on the result mentioned above,it is suggested to replace the layout scheme of the multi-level intake with stoplog gate with that of the conventional one.关键词
