滑坡灾害已成为危及人民生命财产安全的重大问题,确定滑坡体和滑坡面的分布是滑坡治理的关键因素,电阻率层析成像法因对物性差异的界面响应敏感,被广泛应用到滑坡面的探测中。首先,对现有的滑坡地电模型进行概化,得到了4种常见的滑坡的简化模型;其次,针对不同类型的滑坡,采用有限元方法进行了系统的数值正演研究,得到了层析成像法探测滑坡面的响应特征,提出了不同类型滑坡面的快速识别方法。然后,采用最小二乘法开展了反演研究,总结了层析成像法探测滑坡面的反演成像规律,结合数值正演的响应特征,提出了层析成像法探测滑坡面的异常识别特征。最后,在山东沂源西里镇滑坡进行了层析成像法探测,成功探明了滑坡面的分布,表明了层析成像法探测滑坡面是行之有效的,为滑坡的治理方案设计奠定了基础。 Landslide hazard has become a major issue that endangers the safety of people’s lives and property. Determining the distribution of landslides and landslides is the key factor in landslide control. Resistivity tomography is widely used in landslide due to its sensitivity to interfacial differences in physical properties Detection. First of all, the existing landslide geoelectric model is generalized, and four common landslide simplified models are obtained. Secondly, for different types of landslides, the numerical numerical simulation of the landslide is carried out by using the finite element method. Imaging method to detect the response characteristics of landslide surface, put forward different types of landslide fast identification method. Then, the least square method is used to carry out inversion research. The tomographic imaging method to detect the inversion imaging of landslide surface is summarized. Combined with the response characteristics of numerical forward modeling, the tomographic imaging method is proposed to detect the anomalous recognition features of landslide surface. Finally, the tomographic imaging method was used to detect the landslide in Xili town, Yiyuan, Shandong Province. The distribution of the landslide surface was successfully proved. It was proved that the tomography method was effective in landslide detection and laid the foundation for the landslide control scheme design.
