狭窄空间内地下隐伏管路探测效果研究

为确保在狭窄空间内精确探查地下隐伏管路的分布情况,采用高密度瞬变电磁和并行电法2种物探技术对隐伏管路进行综合探测。先以2种物探方法各自的原理和施工布置为依据,分析两者在狭窄勘探空间内理论探查效果;再根据现场条件合理布设物探施工,使2种物探方法优缺互补,减少假异常,缩小异常区范围,准确地找到地下隐伏管路位置,提高物探成果的精细度和可靠性。结果表明:利用精细化物探技术对狭窄空间内隐伏管路进行综合探测、对比解释,能够精确地查找地下隐伏管路位置,效果理想,结果可靠。

Study on Effect of Exploring Underground Concealed Pipeline in Narrow Space

In order to ensure the accurate exploration of underground concealed pipeline in a narrow space, using two geophysical exploration techniques, refined high-density TEM and parallel electrical method to comprehensively detect the concealed pipeline. Based on the principle and construction arrangement of the two geophysical exploration methods, analyzing the theoretical exploration effect of the two methods in the narrow exploration space. Then, according to the site conditions, the reasonable layout and construction can make the two geophysical exploration methods complement each other,reduce false anomalies, narrow the scope of abnormal areas, accurately find the location of underground concealed pipeline, and improve the precision and reliability of geophysical exploration results. The results show that the refined geophysical prospecting technique can be used to comprehensive exploration and comparative interpretation of concealed pipeline in narrow space, and accurately find the location of underground concealed pipeline with ideal effect and reliable results.
