Abstract In the loess plateau beam and gully area, the unfavorable shallow seismic geological conditions such as the Quaternary change of vertical and horizontal direction and the large change of the phreatic surface bring many difficulties to the seismic data acquisition. This paper analyzed the difficulties of seismic data acquisition in the loess plateau beam and gully area. In view of these difficulties, based on the theoretical basis and combined with the construction experience, the technical methods to solve the problem of data acquisition in this area were summarized.
