摘要
利用计算机模拟技术,以直流电法中二极装置为研究对象,讨论了地下均匀无限半空间中存在球形异常体的测深曲线的异常特征和探测深度问题。这里定义了最小、最大、最佳探测可靠异常极距,并讨论了最小、最大、最佳探测可靠异常极距与球体半径、球体中心埋深、相对电阻率的关系,来说明二极装置在球形异常体条件下的勘探深度。
This paper uses the technology of computer modeling,taking double-pole device as the research subjects in the Direct Current Method.The text discusses the problem,which exists in the sphere anomalous body curves of the anomaly characteristics and detecting depths based on the underground of half-space of uniform infinity.This paper defines the min/max and the best abnormal polar distance of the detecting reliable,and discusses the polar distance with the radius of sphere body,the center depth of sphere body and the relative resistivity ratio.The paper illustrates the detecting depth of double-pole device in the condition of sphere anomalous body.
