【摘要】 为了确定辽宁省沈阳市到吉林省白河市高速客运铁路专线(简称沈白铁路)物探线路DK364+400～DK365+050段隐伏断裂带的具体位置和结构特征，采用高密度电法勘探对断裂带的位置和分布情况进行探测。共布置两条长为500 m的平行线路的高密度测线，通过反演得到两条测线电阻率剖面，并辅以剪切波测井结果，得到工区的物探地质解释剖面。通过分析，推断断裂带宽度为50 m,位置分布在物探线路的DK364+700～DK365+750处，走向约为NE 20°,倾向SE。本次勘探查明了隐伏断裂带的位置和产状，并为后续铁路施工提供了具体的断裂带信息，同时表明高密度电法勘探辅以剪切波测井对断裂带进行探测具有较好的效果。更多还原

【Abstract】 In order to determine the specific location and structural characteristics of the hidden fracture zone in the geophysical exploration line DK364+400～DK365+050 section of the high-speed passenger railway line from Shenyang of Liaoning Province to Baihe of Jilin Province(Shenyang-Baihe Railway for short), the authors use high-density electrical exploration to detect the location and distribution of the fracture zone. Two high-density measuring lines with a length of 500 m are arranged in total, and the resistivity profiles of the two measuring lines are obtained through inversion. Supplemented by shear wave logging results, the geophysical and geological interpretation profiles in the working area are further obtained. Through analysis, it is inferred that the width of the fracture zone is 50 m, which is distributed at DK364+700～DK365+750 of the geophysical prospecting line, with a strike of about NE 20° and a dip of SE. This exploration has found out the location and occurrence of the fracture zone, and provided specific fracture zone information for the subsequent railway construction. At the same time, it shows that high-density electrical exploration combined with shear wave logging has a good effect on the detection of fracture zone.更多还原
