| Abstract: | The geological defect evaluation by using seismic tomography are evaluatedis conducted according toaiming at resisting rock of the foundation processing treatment cavities with on elevation 1 785 m in the left bank abutment resisting rock of Jinping I Hydropower Station to provide reinforcement measures.The principle and method of seismic tomography are introduced,and the results of seismic tomography and the quality classification of rock mass on the spot are significantly compared and analyzed.The analytical result shows that it is feasible to evaluate geology defects of bank abutment under the complicated geological conditions by using seismic tomography,and the result is relatively reliable with a promising application. |
