Study On Consolidation Detecting Technology Of Left Resisting Force Body Of Jinping I Powerstation

About less than 25% of the hydraulic resources are well-utilized in China.The rests of them are hidden in mounts and difficult to development in the past.With the time passing, the energy policy of Chinese government has oriented to futher utilize the hydraulic resources to decrease the depending on thermal power.For the further development of them, many power station need to process the basement of the dam because of the complexity of the geologic conditions.Jinping I power station has a very complex geologic condition,so it need consolidate to improve the basement of the dam for the safeness of the dam。To direct the consolidation,Jinping I has done many experiments to test the effect of the consolidation. Using the experiment results, we contrast many kinds of consolidation detecting methods and refer a better one as the direction method in this paper. And some important standpoints and conclusions are made.Firstly, according to the revealed geologic condition of the left resistion force body, we grade the terranes, try to detect the spacial distributions of the he left resistion force body and evaluate the stability of the terranes.Second is to evaluate the technological adaption of five kinds of consolidation detecting methods, which including single-hole sound-wave test, panorama image, CT scan and so on.Thirdly, we focus on the correlation of the the different detecting methods.Finally, after the analysis of detecting methods,we refer a better one as the main testing method and establish the quality tesing criteria fitting to resisting force body of Jinping I.
