Technology of Detecting Dyke’s Hidden Danger Using Time-lapse High-density Resistivity Method
摘要
Abstract
The development of time-lapse prospecting technology is briefed through summarizing the methods of de-tecting hidden dangers of dykes. The working principle of time-lapse high-density resistivity method is expounded from aspects of observation mode, data acquisition and processing, inversion and image rendering, as well as anom-aly judgment method. The effectiveness of time-lapse high-density resistivity method in detecting hidden dangers of dyke is examined by 3D forward simulation of two typical hidden dangers, namely, cave and leakage. Moreover, pilot demonstration of the techniques of time-lapse high-density resistivity method is presented based upon engineer-ing practice. Furthermore, the possibility of time-lapse prospecting technology in dynamic detection of hidden dan-gers of dyke are evaluated in conditions of long distance of dyke and concealing, abrupt, lasting, and lowly detecta-ble dangers.关键词
