摘要
高密度电法是近年来出现的一种物理勘探新方法,它集中了电剖面法和电测深等普通直流电阻率方法的特点,不仅可以提供地下一定深度范围内电性的横向变化情况,而且还可以提供垂向电性的变化特征。广泛应用于地质找矿、石油勘查、地热资源调查、不良地质现象勘察等领域。随着技术的不断成熟,它也日益在工程勘察领域中不断使用。以镇江市宝塔山桥为工程实例,说明其在工程勘察中的应用。
High density resistivity method is a new method for physical investigation,which combines the characteristics of electrical profiling and electrical sounding.It can not only supply the horizontal change situation at the range of underground,but also vertical electrical property.At present,it is widely used in geological prospecting,petroleum exploration,geothermal investigation and bad geological phenomenon exploration.Taking Baota Mountain Bridge in Zhenjiang for example,the application of high density resistivity method in engineering exploration is introduced.
