The Research On Rapid Detection And Calculation Method Of Reservoir Capacity And Sedimentation Volume

Reservoir project plays a huge benefit in flood defense, runoff regulation, andrational use of water resources and so on. The change in capacity and sedimentationof the reservoirs is concerned by water conservancy power department. Correct andrapid determination of capacity and sedimentation of dam plays an important role inensuring the safety and plan, scheduling, power generation.The main purpose of the thesis is to introduce the GPR technique, with thecharacteristics of fast, continuous, high precision detection, into the sector. The papermainly solve the water electromagnetic wave velocity error correction, signal energyfrequency compensation, many jamming signal elimination, underwater interface andsilt bottom interface radar image recognition technology problems, exploration ofimplementation of the continuous orientation, the scene the work method, detectingdata processing and capacity calculation and sedimentation practical problems such as,in order to form a complete set of detection methods and software system.This paper makes some theory and material achievements. The theoreticalachievements are as follows:(1) For the first time at home and abroad in thesystematic study of the temperature and salinity, turbidity water to the influence of theelectromagnetic wave speed is given in the water of the electromagnetic wave speedadjustment typical curve.(2) For the first time at home and abroad determine the threekinds of typical soil dielectric model, which are based on the determined the GPRdielectric constant.(3) Research and develop the integrated treatment technology ofhorizontal filter, forecast deconvolution filter and signal energy frequencycompensation, hold down the radar detection signal in the cross effectively, improvethe detection profile resolution, realize the deep waters of the interface layerdeposition effective detection; the research results meet the domestic leading level.The material achievements are as follows:(1) Develop the system of water GPR data processing and capacity, sedimentation calculation, fill the blank domestictechnology acquire one software works copyright.(2) For the first time in Chinacompile the water GPR detection technology process.
