工程地质中的声波CT层析成像技术

Sounding TomographImaging Technology in Engineering Geology

ＣＴ技术在工程地质中主要用以解决地质构造、地层结构、工程地质力学等地质问题。结合实际讨论了声波层析成像中设备的选择、观测系统的建立和资料处理等问题。工程地质中的实际使用证明其效果良好。与工程地质中使用的其他物探方法比较，ＣＴ具成图效果好、直观。

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.
