大功率多道密集排列滚动方式三极测深在地灾隐患勘查中的应用

Application of high power multi-channel array rolling tri-electrode sounding to detection of hidden geo-disasters

大功率多道密集排列滚动方式三极测深是在传统电测深法基础上经过装置变换、改进而来的新型实用测深技术,相比常规的高密度直流电法,具有探测深度大、横向分辨率高、提供信息丰富(可同时提供视电阻率、充电率)、抗干扰能力强等特点,近几年广泛应用于多金属矿勘查、地质隐患调查、工程地质探查等领域,文章介绍了该方法的装置特点和工作流程,并列举多项勘查实例说明该方法在地灾隐患勘查中的应用效果。

High power multi-channel array rolling tri-electrode sounding is a new geophysical exploration technique developed from the troditional electric sounding method and is characterized by deeper detec- tion, high lateral resolution, large volume information supply （contemporaneous supply of resistivity andchargeability） and strong anti-noise thus widely applied to poly-metallic ore deposit exploration, hidden geo-disaster investigation and engineering geology etc. This paper introduces the assemblage and working process and application cases to hidden geo-disaster investigation.
