摘　　要：工程项目实施前,确定工区地下空间分布详情是不可缺少的工作内容。三维高密度电法观测系统的布设难度大,使用常规电法仪进行采集耗时较长,在真实复杂地质条件下,应用难度大。利用并行电法采集技术,可以达到高效采集数据的目的。为准确查明某磷石膏堆场下部及周边可能形成渗漏管道的区域的三维形态,结合实际地质情况,采用并行电法进行数据采集,获取测区内真三维观测系统下的三维电法勘探数据体,然后对数据进行带地形三维反演处理和解释。结果表明:三维并行高密度电法探测场地地下空间分布具有一定的有效性和准确性。本次现场探测共圈定了5个异常区。与钻孔揭露资料吻合,为后期指导防渗帷幕施工提供准确依据.Before the implementation of engineering projects,it is essential to determine the detailed distribution of underground spaces in the work area.The deployment of a 3D high-density electrical observation system is difficult,and using conventional electrical equipment for acquisition is time-consuming,especially in complex geological conditions.By using parallel electrical acquisition technology,efficient data acquisition can be achieved.To accurately determine the three-dimensional morphology of the area where possible leakage pipes may form in the lower part and surrounding areas of a phosphogypsum stacking yard,parallel electrical acquisition was used to collect data,combined with actual geological conditions.The three-dimensional electrical exploration data volume under the true three-dimensional observation system in the measurement area was obtained,and the data was processed and interpreted with three-dimensional inversion with terrain.The results show that 3D parallel high-density electrical observation can effectively and accurately reveal the distribution of underground spaces on the site.A total of 5 abnormal areas were delineated during the on-site exploration.The results were consistent with the drilling exposure data and provided accurate basis for guiding the construction of anti-seepage curtains in the later stage.
