【摘要】 为解决考古、工程地质和地下水污染勘查等领域探测靶体与周围介质电性差异不大的地质问题,提出了一种扰动电阻率成像方法。通过对商丘地区的地下夯土城墙的应用表明,该方法有效消除了夯土城墙的傍侧效应及地下水噪声的影响,清晰、直观地揭示出地下夯土城墙的埋深范围及几何形态。更多还原

【Abstract】 To solve geological problems with no sharp resistivity contrast between geological target and surrounding radium, such as, the exploration of archaeology, geological engineering and underground water pollution, a perturbation image method of resistivity is presented. Through the application in underground walls in Shangqiu area, the method effectively reduces geological noise caused by underground water and clearly shows the position and the shape of underground walls.更多还原
