层析成像技术(CT)在拱坝质量检测中的应用

Application of computer tomography technology in the quality check of arch dam

近年来 ,地震层析成像技术 (CT)发展很快 ,根据层析成像技术的方法和原理 ,将其运用到水电工程检测中 ,取得了令人满意的成果。在实际工程中 ,对拱坝的质量进行检测和评价 ,取得了很好的效果。与常规物探相比 ,井间走时层析成像能获得更多的信息 ,将其与钻探相结合 ,能够大范围地评价工程质量。

The earthquake computer tomography technology and its methods and principles in the engineering check, in combination with actual project, have been applied in the check and assessment of arch dam quality and very good effectiveness has been gained. Compared with those common methods, the computer tomography among wells can gain more information. When such technology is combined with boring, it can assess the quality of project in a large area.
