Abstract:
Based on the background of active fault detecting in the major study area of Lingshan Guangxi, this paper introduces the work thought and comparison & application to the methods of geophysical prospecting in the buried area. Based on the comprehensive analysis to the previous data, the line R located at Dalong village Shitang town is selected to be the site for the integrated test exploration. According to the work thought of layered detecting, the high density resistivity method has been used firstly, followed by the seismic imaging method, refraction waves method and ground penetrating radar, tracing the upper breakpoint of the fault located at the depth of 2 m. Finally, with the help of large-scale investigation pit, the upper breakpoint of the fault has been exposed at the depth of 1 m, which is a holocene active fault. The comprehensive detecting result shows that the methods combination of high density resistivity method, seismic imaging method and ground penetrating radar meet the need of the active fault detecting in the major study area of Lingshan.
