摘要
该文以相同工区、相同测线上采用高密度电阻率法和地震折射波法相结合进行勘探为例,对划分地层界面,确定覆盖层厚度进行了综合对比与解释,结果表明:折射波法弥补了高密度电法分层的不足,而高密度电法弥补了折射波法对层面周围环境无法得知更详细地质情况的缺陷。当地球物理条件较差时,地震折射波法比高密度电法的勘探效果好。如果这两种物探方法相互补充,可得到更准确的地质构造。
Exemplified by combining the high density resistivity method with seismic refracted wave method to prospect in the same work area and traverses, this paper gives a synthetical contrast and interpretation to divide the stratum interface and determine the thickness of overburden. The results indicate that the refracted wave method can remedy the deficiency of high density resistivity method in dividing the stratum, and high density resistivity method may overcome the shortcomings of the refracted wave method in exploring more detailed geo- logical condition of layer＇s surrounding environments. When the geophysical conditions are worse, the seismic refracted wave method will get a better exploration result. The two methods complement with each other, so as to obtain more exact geological structure.
