Study On The Feasibility Of Banduo Hydropower Station

Hydroelectricity is a kind of green resource for sustainable development.Once the hydroelectrical power station is completed,the operating costs are relatively down.Compared with traditional energy resources,hydroelectricity has more advantages.China is rich in its hydropower resource.With the development of China's economic power,the needs of hydroelectricity are increasing.As a result,the number of planned hydroelectical power station is increasing.Because of the huge investment in the early stage,long-term profits,high requirement of professional technology,it is necessary to make a full investigation of the feasibility.However,the history of the feasibility research of hydroelectrical power station is short,so there are only a few references that we can use.In addition,according to the different area situation of each project,it is also necessary to make feasibility analysis,judgment and optimization of various aspects of the regional geological conditions and engineering geological problems what are related to the design and construction of hydroelectricity power station in order to provide risk,security,economy and other feasible indicators for the construction of the station.This paper used Banduo hydroelectricity power station of Yellow River as an example.It made a research on the determination of feasibility of the project according to following aspects: the regional geological condition,the engineering geological conditions in reservoir area,the comparison and selection of dam sites,the engineering geological conditions of selected dam site area,the engineering geological condition and comparison of each dam line,the engineering geological conditions of hub buildings,and the natural building materials of engineering.The result shows that there are no regional faults or active faults passing through the Banduo Reservoir.And the lithology of the reservoir basin are sandstone and slate which will not leak reservoir water to the deep,and it does not have the leakage conditions earthquake leakage so there will be no reservoir-induced earthquake.The result also shows that the reservoir area conditions are pretty good.Among the upper,middle and lower dam sites,the engineering geological conditions of the middle site are still good and there are no major engineering geological problems.It is convenience to construct in the middle site,and has a higher utilization of the water source.Combined with the scale of the power station,the adaptability is better.As a feasible solution,the upper line is better.There are no engineering geological problems in hydraulic structures,natural building materials are sufficient,and it also meets the requirements of regulatory indicators.The seven feasible aspects provide reliable basis for further design and construction of Banduo Hydroelectricity Power Station.And the research results have important reference significance for the determination of the feasibility of similar projects.
