高密度电阻率法基岩面三维技术研究

Research on 3D Technology of High Density Resistivity Method for Bedrock Surface

传统的利用高密度电阻率法确定土岩分界流程是:通过在地表布置物探测深剖面,采用高密度电阻率测深仪器测量地表以下岩土体的二维视电阻率断面图,然后根据地质情况推断解释,最后获得二维测线上的土岩分界面。可以看出传统方法在基岩面探测方面得到的成果单一,基岩面展示不够直观。本文为了解决现阶段基岩面探测中遇到的问题,降低工程成本,并提倡"提高效率,降低费用,绿色节能、安全环保",在原有工作的基础上,研制出一种切实可行的方法来解决此类问题。

The traditional process of determining the soil-rock boundary by using high-density resistivity method is to use high-density resistivity sounding instrument to measure the two-dimensional apparent resistivity cross-section of rock and soil below the surface by geophysical sounding profiles,then infer and interpret according to geological conditions,and finally obtain the soil-rock interface on the two-dimensional surveying line.It can be seen that the results obtained by traditional methods in the detection of bedrock surface are single,and the display of bedrock surface is not intuitive enough.In order to solve the problems encountered in the detection of bedrock surface at the present stage,reduce engineering costs,and advocate"improving efficiency,reducing costs,green energy saving,safety and environmental protection",based on the original work,a practical method is developed to solve such problems.
