高密度电阻率法在断层勘察中的应用

The Application of High Density Resistivity Method in Prospecting Active Fault

相对传统的钻探勘察,工期较短的工程需要一种更为高效的勘察方法来勘察活动断层,规避工程风险,本文结合工程实例论述了高密度电阻率法在活动断层勘察中的准确性及高效性;高密度电阻率法是一种高效、灵活、经济的物探方法,相同条件下具有钻探方法难以达到的横向分辨率;结合钻探勘察成果的准确性及唯一性,该方法在探明活动断层的横向分布、产状等参数方面表现出了很好的适用性;该方法成果直观,是一种在满足相对精度的条件下,简单灵活,经济高效的勘察方法。

Compared with the traditional drilling,it needs a more efficient method to prospect active fault for the short construction period project,avoid engineering risk.Combined with the engineering project example,this paper discusses the accuracy and efficiency of high density resistivity method in the prospecting of active fault;High density resistivity method is a geophysical prospecting method of high efficiency,flexible,economical.It has higher lateral resolution than drilling method under the same conditions,with the uniqueness and accuracy of drilling investigation results,the method is suitable for prospecting the transverse distribution,occurrence of active fault;this method has visual results and it is a simple,flexible,economic and efficient method when meeting the requirement of relative precision.
