近来,各种电层析成像技术已经得到改进,很快地目前已能买到有效的工业用系统。新反演算法产生了电图像,它们比以前曾有过的更精确地模拟了一个二维或三维地下界面。近三年来,在德国、英国和美国进行的电层析成像调查已产生了显著成果。 由于野外技术已经变得更精确并且数据采集速率也增加了,电成像已适合于浅地下界面的时延调查。下面的可行性研究说明了该技术的效率以及它作为地下水调查中一种重要工具 Recently, various electro-tomographic imaging techniques have been improved and very quickly, effective industrial systems have been available. The new inversion algorithm produces electrical images that simulate a two-dimensional or three-dimensional subsurface more accurately than ever before. In the last three years, the investigation of electrochirography in Germany, the United Kingdom and the United States has yielded remarkable results. As field technology has become more accurate and data acquisition rates have also increased, electrical imaging has become well suited for time-of-flight investigations of shallow subsurface interfaces. The following feasibility study illustrates the efficiency of the technology and its role as an important tool in groundwater investigations
