中文摘要：
通过节理岩体注浆过程中不同部位的地电场响应特点试验,获得了岩体注浆过程中地电场参数瞬时响应规律。对采集数据运用视电阻率反演技术,得到了三维数据体,并能直观地看出电阻率的变化,从而分析浆液扩散及对岩土体的改造情况。自然电位和激励电流对浆液具有很好的敏感度,基于一定的电极排列及数据采集方式,可以很好地跟踪浆液扩散状态。了解注浆过程中地电场参数的变化有助于对浆液扩散规律的认识,也在一定程度上验证了注浆改造效果。
英文摘要：
Through the response characteristics test for different parts of the geoelectric field during the grouting process of jointed rock mass,the instantaneous response law of geoelectric field parameters was achieved. By using apparent resistivity inversion technique to collected data,the 3D data were got,the change of resistivity could be observed directly,a nd the slurry diffusion and reconstruction condition of rock mass were analyzed. Natural potential duration and exciting current have a good sensitivity to grouting,which could be used to track the slurry diffusion state based on a certain arrangement of electrodes and data collection methods. Understanding the variation of geoelectric field parameters in the grouting process is helpful to summarize the slurry diffusion law and verify the effect of grouting reconstruction to a certain extent.
