Research on the application of shallow seismic reflection wave method and ground penetrating radar method in detecting underground air defense tunnels
Due to the lack of relevant data of early civil air defense projects,a number of blind spots have been formed.In this paper,shallow seismic reflection wave method and geological radar method are used to locate and detect the blind area of underground air-raid shelter in Ningbo area of Zhejiang Province,and the feasibil-ity of non-destructive testing under full water and after pumping is analyzed.The results show that the appli-cation of the two methods can basically realize the positioning detection of the buried depth of the air-raid shelter.The reflected signal is clearer after the water is drained.The environmental interference should be reduced during the field investigation and application.The test analysis parameters should be optimized.The results need be verified.
