高密度电法在滨海构造断裂区勘察中的应用

Application of high-density electrical method in exploration of coastal structural fault zone

在对青岛胶州湾附近某重点项目进行初步勘察时发现场区内的地层有明显的变化,初步判定沧口断裂经过该场区。为了精确查明沧口断裂在场区的分布位置及展布宽度,采用高密度电法并结合钻孔资料的方法,达到综合确定断裂在场区的分布范围的效果,其研究成果对于类似工程的勘察具有借鉴参考作用。

During the preliminary survey of a key project near Qingdao Jiaozhou Bay,it was found that there were obvious changes in the stratum within the site. It is preliminarily determined that the Cangkou fault passes through the field. In order to accurately determine the distribution position and spread width of the Cangkou fault in the field area,the high-density electrical method and the method of combining drilling data were used to comprehensively determine the distribution range of the fault in the field area.It has a guiding role for reference.
