Study On Dam Site Layout Plan Of Digou Reservoir Hub Project

By combining the situation of water resource in the Fulahun River basin,At present,there is no large water storage project along the trunk stream of Fulahun River,the actual conditions of Erjiagou pivotal project,as well as landform of Erjiagou reservoir location,this paper makes the comparative study for layout plan of damsite in the Erjiagou reservoir project.The main research contents are as follows:1.Describe the landform overview of location where Erjiagou reservoir is planned to be built in Tonghe County,analyze general situation of Fulahun River basin and related hydrologic situation,and introduce the development and planning of Erjiagou reservoir project.2.Analyze the elementary survey of Erjiagou reservoir project such as landform,geology,external traffic,project layout and construction conditions.3.On the basis of analysis on general layout of damsite of Erjiagou reservoir,and the conditions such as landform,geology,project and layout,quantities and investment,we plan to compare two layout plans,respectively the upper damsite layout plan and the lower damsite layout plan,to meet the layout principle.4.The lower damsite layout plan is recommended through comparison and selection of quantities,investment,construction progress,electric energy in construction period,aerial drainage condition,operation condition and construction conditions,etc.
