| China’s water conservancy industry has developed rapidly,and more than 98,000 reservoirs have been built since the mid-1960 s.The massive construction of these water conservancy measures has improved the comprehensive flood control capacity and water resources regulation level of the rivers,and also played a huge role in water supply,irrigation,flood control,and power generation.These water conservancy measures played an irreplaceable role in the construction of farmland water conservancy,and at the same time led to the rapid development of the entire social economy.However,due to the constraints of the reservoir construction era and the fact that the project has been in disrepair for many years,most of the reservoirs have a certain degree of erosion,damage,aging and other diseases,and cannot be operated,and there are certain safety risks.The disease will obviously affect the normal operation of the reservoir.Without effective treatment,it is easy to endanger the lives of the people downstream of the reservoir.Therefore,in order to solve this problem,it is necessary to study the dangerous reservoir project and carry out the reinforcement design.In the research process,this paper selected Fuxin City Fosi Reservoir Project as a case,conducted investigation and analysis and collected relevant materials in detail,and carried out certain theoretical and practical analysis.The reservoir runoff and similar sedimentary area method were used to analyze the reservoir runoff and storage sediment.The flood calculus analysis was designed based on the integrated instantaneous unit line method,and the height of the flood level was obtained.Based on the finite element method seepage stability analysis,the dam safety coefficient after reinforcement is greater than the minimum safety factor,which provides the basis for dam stability analysis.Through the value engineering theory,the advantages and disadvantages of the dam reinforcement anti-seepage scheme were compared,and the curtain grouting anti-seepage reinforcement scheme was finally determined.It provides a research idea for engineering reinforcement research.According to the relevant engineering practice experience,the process of reinforced and ill-treated reservoirs is very complicated.It is not a simple and feasible solution to build a new reservoir.As the operation time of the reservoir continues to increase,some of the effective operation functions have been lost,and some safety hazards have appeared.Therefore,it is necessary to repair and reinforce these reservoirs and eliminate the related safety risks.The results of this study can be the same.Type engineering provides a certain reference. |
