Abstract: The hammering small?refraction method was used in the near?surface survey of the Qiharigetu Depression in Erlian Basin.The parameters of geometry which are suitable for the study area were obtained,and the interpretation of practical small?refraction survey showed the close correlations with the interpretation of small?refraction record based on explosive source,borehole data,and the meas?urement results of high density resistivity method.Meanwhile,the hammering small?refraction method will improve the efficiency of the near?surface survey,and make the job more convenient and the cost lower.This method therefore has higher practical value in this area.
