Study On Design Of Yangzhuang Reservoir Reinforcement Project

China has a large number of reservoirs.With these reservoirs,the comprehensive flood control capacity of rivers has not only been enhanced,but also the control level of water resources has been improved,which can achieve great benefits in flood control,irrigation,water supply and other aspects.However,most of these reservoirs have a large number of dangerous reservoirs due to the background problems of construction years and disrepair for a long time,which seriously affects the benefits of the project and the social security of the downstream.Therefore,it is of great practical significance to carry out the reinforcement design and Research on the dangerous reservoir engineering.Yangzhuang reservoir was built in 1972 with a total storage capacity of 2.136 million m3,which is a small(I)reservoir.The main functions of the reservoir are flood regulation,mud retention,irrigation and ecological balance protection.The reservoir project is mainly composed of earth dam and water conveyance structure.According to the conclusion of dam safety appraisal,the dam belongs to three types of dam,which has major hidden danger and needs reinforcement.In this paper,combined with the specific project,based on the collection of data,according to the relevant design specifications,combined with the existing experience to carry out a certain theoretical analysis,and clear Yangzhuang reservoir related dangerous problems,the research content is as follows: Based on the analysis of the current situation of the reservoir,this paper discusses the necessity of danger elimination and reinforcement,analyzes the hydrological and geological conditions of the reservoir,determines the project task and construction scale,determines the overall scheme of heightening the dam body and adding the bank spillway through the scheme comparison and selection,and completes the reconstruction design of the upstream heightening dam body,the spillway design and other buildings with disease problems Physical design.In view of the problems of many kinds of soil in the heightening of the dam on the silt laden river,this paper analyzes the variation law of the seepage field of the dam body under the different combinations of the permeability coefficient of the foundation,silt,the old dam body and the new dam body.Through the seepage analysis of soil material allocation scheme in No.5,the best form of soil material allocation is obtained.
