地质灾害四维电阻率采集成像监测技术研究

Research on technique of four-dimensional resistivity acquisition and imaging monitoring for geological hazards

电法勘探技术是自然地质灾害和地下污染物勘查的有效技术手段之一。但现有的勘探技术因同步管理电极数量少、无法并行处理海量数据和测量过程耗时过长等缺点,难以在自然地质灾害预测和地下污染物勘查过程中提供及时、准确的地下目标体电性信息的变化,使电法法勘探在该领域发挥的作用受到限制。因此,文章结合DEM-3型分布式电法仪设计一种能对地下目标体电性数据的实时、大面积、准确监测预测的四维电法勘探技术。

The electric prospecting technique is one of the effective techniques for the exploration of natural geological hazards and underground pollutants. But the existing exploration technology for synchronization management electrode less quantity, not parallel processing disadvantages such huge amounts of data and measurement process takes too long, difficult in the natural geological disaster forecast and provide timely and accurate in the process of pollutants to the exploration of underground underground target body electrical information change, make the role of electrical prospecting in this area is restricted. Therefore, this paper combines DEM-3 distributed electrical method instrument to design a four-dimensional electrical method exploration technology that can monitor and predict the electrical data of underground target body in real time, large area and accurately.
