摘要
网络并行电法已成功应用于地质体勘察,以某地区域地层勘察工程为研究对象,从基于Levenberg Marquardt反演原理及模型构建,计算过程将光滑约束模型及自适应调节阻尼因子实施电阻率数据反演,结合高效的数据采集方法获得了某地区区域深120 m范围内的探测结果,反演数据视电阻率空间分布异常区域为YC1和YC2。研究结论:探测区域揭示存在2个相对低电阻异常区,分别表现为溶洞发育区和富水地层,区域整体呈现西高东低基岩界限明显的特征,与实测钻探显示基本一致,结论可指导后期工程规划设计。
The network parallel electrical method has been successfully applied to geological exploration. Taking a certain regional stratigraphic exploration project as the research object, based on the principles of Levenberg Marquardt inversion and model construction, the calculation process implements resistivity data inversion using the smooth constraint model and adaptive adjustment of damping factors. Combining efficient data collection methods, the detection results within a depth range of 120 m in a certain regional area were obtained. The inverted data identified anomalous regions in resistivity spatial distribution as YC1 and YC2. Research conclusion: The detection area reveals the presence of two relatively low-resistivity anomalous zones, representing Karst cave development areas and aquifer-rich formations. The overall region shows a distinct west-high and east-low bedrock boundary, consistent with actual drilling results. The conclusions can guide later-stage project planning and design.
