| Abstract: | CT tomograph imaging technology,firstly used in petroleum prospecting midterm of 1980s,have been widely used in the engineering geology etc.to detect many engineering geologic settings.CT technology could be used to detect the problems such as geologic tectonics,stratigraphic structure and engineering geomechanics in the engineering geology.The sounding CT and electromagnetic wave CT are two conventional methods among CT technology.The sounding CT tomograph imaging method includes the selection of sounding tomograph imaging facilities,establishment of observation system and data treatment.The practical application of the technology in the engineering geology demonstrates that combined with other geophysical prospecting methods,CT technology has good imaging effectiveness and directreading out of influences from surface obstacle matters etc.Combined with engineering geologic data,CT technology can offer direct basis for the design and construction of engineering. |
