摘要
以二连盆地齐哈日格图凹陷为试验区,开展基于锤击震源的小折射地表调查试验研究,得到了一套适用于该区的锤击小折射法的观测系统参数,并开展了实际地表调查工作,锤击小折射解释结果与井炮小折射记录的解释结果、钻孔资料、高密度电法测量结果具有较好的对应关系,精度较高,同时锤击小折射法可提高地表调查工作的效率,使工作更加便捷,成本更加低廉,具有较高的实用价值。
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 measurement 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.
