摘要
近些年来,工程建设中所面临的地质、地形条件越来越复杂.跨孔直流电阻率CT把供电电极和测量电极分别置于两孔中,通过"跨孔对穿"的方式来探测接近电极的目标体.主要研究在对高阻异常体的探测过程中"电阻率CT"这种方法的可行性.通过正演模拟的方法来确定其在高阻异常体探测过程中不同影响因素的对比效果,探讨影响探测效果最主要的2个因素(电极距和孔间距)对高阻异常体探测的影响.
Abstract
In recent years,the geological and topographical conditions faced in engineering construction have become increasingly complex.Cross hole DC resistivity CT places the power supply electrode and the measurement electrode in two separate holes,and detects the target body approaching the electrode through"cross hole penetration".The feasibility of the"resistivity CT"method in the detection of high resistance anomalous bodies was mainly studied.The forward simulation method was used to determine the comparative effect of different influencing factors in the detection process of high resistance anomalous bodies,and to explore the influence of the two main factors that affect the detection effect(electrode distance and hole spacing)on the detection of high resistance anomalous bodies.
