In recent years,a large number of large-scale water conservancy and hydropower projects are or will soon be put into construction. In these projects,there are a lot of long large tunnels and extra large underground powerhouse( chamber group). In the construction process,often accompanied by water-bursting and mudbursting,landslides,rock burst and other safety incidents. Aiming at the problem of the lack of adaptability of the commonly used advanced geological prediction method,for the first time,8 kinds of commonly used methods are used to carry out the field test research on the same subject. At the same time,the detection results of each method are analyzed and compared. And we put forward a new vertical reflection method observation system with concentric circle and the same offset. At the same time,the research on the adaptive test of the electric spark source is carried out.
