Abstract The surface and geological conditions of Qiangtang basin is complicated,the data signal to noise ratio is extremely low,the folding of strata is serious,and hence the seismic data processing is very difficult. In order to grasp the characteristics of interfering waves in the region more effectively, the authors selected the appropriate seismic exploration parameters and put forward the appropriate box wave investigation method.Through the box wave analysis, it is found that the regular interference wave is well developed with obvious regularity,but the speed of energy and other aspects show evidentdifferences.Through the combinational indoor analysis, the authors detected that the accepting combination form has a rather great impact on the data, and such parameters as the number of received combinations, the base distance and graphics also affect the data quality.
