摘要
高密度电阻率法是近年来在堤防隐患探测中广泛应用的地球物理方法.它以岩土体的导电性差异为基础,研究人工建立的地中稳定电流场的分布规律,进而确定隐患异常部分的位置、规模.利用高密度电阻率测量系统对堤防进行无损普查,可以准确地解释出堤防隐患的空间分布及其规模.介绍了E60CN型高密度电阻率测量系统的特性,工程实测资料解释与地质资料对比分析证明该方法测试精度高、结果直观,符合工程要求,实用性强.
High density resistivity(HDR) is a new geophysical technique which is used in dyke hidden trouble(DRT) survey broadly in recent years.This method is based on the difference of the rock and soil electrical conductivity,and can help the surveyor to make sure the place and the scale of the hidden body with different electrical conductivity through analyzes rules of the distributing of electric current in the stable artificial electric field.High density resistivity(HDR) measuring system can be used to do general dyke survey without destroys and to explain the distribution and scale of the hidden troubles of the dyke accurately.The characteristics of E60CN high density resistivity measuring system is introduced in the essay,which is proved to be accurate,objective and practical after the comparison and analysis on project data and geological materials.
